In these cases, high-dose dobutamine may be used to chemically increase heart rate. [11] If dobutamine is insufficient for this purpose, atropine be added to reach goal heart rate. [11] Dipyridamole is an alternative to dobutamine but it is less effective in detecting abnormalities. [25] While exercise echocardiograms are more effective in detecting coronary artery disease, all forms of stress echocardiograms are more effective than exercise EKG in detecting coronary ischemia secondary to coronary artery disease. [11] If stress echocardiography is normal, risk of future adverse cardiac events is low enough that invasive coronary angiography is not needed. [25] Coronary angiography [ edit ] A coronary angiography is performed after a stress test or EKG shows abnormal results. [26] This test is very important in finding where the blockages are in the arteries. [20] This test helps determine if an angioplasty or bypass surgery is needed. [27] Coronary angiography should only be performed if a patient is a willing to undergo a coronary revascularization procedure. [28] During this test the doctor makes a small incision in the patient's groin or arm and inserts a catheter. [26] The catheter has a very small video camera on the end of it so that the doctor can find the arteries. [20] Once he/she has found the arteries, he/she injects a dye in them so that he/she can detect any blockages in the arteries. [26] The dye is able to be seen on a special x-ray machine. [20] The test takes one to two hours. ... Long and short acting nitrates are one option for reducing anginal pain. [6] Nitrates reduce the symptoms of angina by dilating blood vessels around the heart, which increases oxygen-rich blood supply to the muscle cells of the heart. [39] Veins are also dilated, which reduces return of blood to the heart, easing strain on the heart muscle. [39] Short-acting nitrates can be taken upon the onset of symptoms and should provide relief within minutes. [6] Nitroglycerin is the most common short-acting nitrate and it is applied under the tongue. [6] Long acting nitrates are taken 2-3 times per day and can be used to prevent angina. [6] Beta-blockers may also be used to reduce the incidence of chronic angina. [6] Beta-blockers prevent episodes of angina by reducing heart rate and reducing the strength of contraction of the heart, which lowers oxygen demand in the heart. [6] Coronary revascularization [ edit ] In individuals with symptoms that are not well controlled with medical and lifestyle therapy there are invasive options available including percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG). [28] PCI involves placing a stent to relieve coronary artery blockages. [12] CABG involves grafting new blood vessels to provide a new route for blood flow around the blocked vessel. [12] Choice of treatment is based on the number of coronary vessels with blockages, which vessels are effected, and the medical history of the patient. [28] There is not sufficient evidence to suggest that PCI or CABG provides a mortality benefit in individuals with stable coronary ischemia. [14] The long term efficacy of these procedures in terms of reducing symptoms is still in question. [6] [14] References [ edit ] ^ "Myocardial ischemia" . ... Coronary Ischemia" . Shmc.org .

They proposed that the rats who witnessed the electrical shocking of other rats were under emotional stress which may have caused the bruxism-like behavior. [23] Genetic factors [ edit ] Some research suggests that there may be a degree of inherited susceptibility to develop sleep bruxism. [1] 21–50% of people with sleep bruxism have a direct family member who had sleep bruxism during childhood, suggesting that there are genetic factors involved, [26] although no genetic markers have yet been identified. [1] Offspring of people who have sleep bruxism are more likely to also have sleep bruxism than children of people who do not have bruxism, or people with awake bruxism rather than sleep bruxism. [27] Medications [ edit ] Certain stimulant drugs, including both prescribed and recreational drugs are thought by some to cause the development of bruxism, [1] however others argue that there is insufficient evidence to draw such a conclusion. [28] Examples may include dopamine agonists , dopamine antagonists , tricyclic antidepressants , selective serotonin reuptake inhibitors , alcohol , cocaine , and amphetamines (including those taken for medical reasons). [7] In some reported cases where bruxism is thought to have been initiated by selective serotonin reuptake inhibitors, decreasing the dose resolved the side effect. [15] Other sources state that reports of selective serotonin reuptake inhibitors causing bruxism are rare, or only occur with long-term use. [29] [23] Specific examples include levodopa (when used in the long term, as in Parkinson's disease ), fluoxetine , metoclopramide , lithium , cocaine , venlafaxine , citalopram , fluvoxamine , methylenedioxyamphetamine (MDA), methylphenidate (used in attention deficit hyperactive disorder ), [28] and gamma-hydroxybutyric acid (GHB) and similar gamma-aminobutyric acid -inducing analogues such as phenibut . [28] Bruxism can also be exacerbated by excessive consumption of caffeine , [28] as in coffee, tea or chocolate. Bruxism has also been reported to occur commonly comorbid with drug addiction . [23] Methylenedioxymethamphetamine (MDMA, ecstasy) has been reported to be associated with bruxism, [28] which occurs immediately after taking the drug and for several days afterwards.
Overview Bruxism (BRUK-siz-um) is a condition in which you grind, gnash or clench your teeth. If you have bruxism, you may unconsciously clench your teeth when you're awake (awake bruxism) or clench or grind them during sleep (sleep bruxism). Sleep bruxism is considered a sleep-related movement disorder. People who clench or grind their teeth (brux) during sleep are more likely to have other sleep disorders, such as snoring and pauses in breathing (sleep apnea). Mild bruxism may not require treatment. However, in some people, bruxism can be frequent and severe enough to lead to jaw disorders, headaches, damaged teeth and other problems. Because you may have sleep bruxism and be unaware of it until complications develop, it's important to know the signs and symptoms of bruxism and to seek regular dental care.

Direct scaling tests show the ability to discriminate among different intensities of stimuli and whether a stimulus of one quality (sweet) is stronger or weaker than a stimulus of another quality (sour). [28] Direct scaling cannot be used to determine if a taste stimulus is being perceived at abnormal levels. In this case, magnitude matching is used, in which a patient is asked to rate the intensities of taste stimuli and stimuli of another sensory system , such as the loudness of a tone, on a similar scale. [28] For example, the Connecticut Chemosensory Clinical Research Center asks patients to rate the intensities of NaCl, sucrose, citric acid and quinine-HCl stimuli, and the loudness of 1000 Hz tones. [28] Other tests include identification or discrimination of common taste substances. ... In addition, the analysis of saliva should be performed, as it constitutes the environment of taste receptors , including transport of tastes to the receptor and protection of the taste receptor. [34] Typical clinical investigations involve sialometry and sialochemistry. [34] Studies have shown that electron micrographs of taste receptors obtained from saliva samples indicate pathological changes in the taste buds of patients with dysgeusia and other gustatory disorders. [35] Treatments [ edit ] Artificial saliva and pilocarpine [ edit ] Because medications have been linked to approximately 22% to 28% of all cases of dysgeusia, researching a treatment for this particular cause has been important. [36] Xerostomia , or a decrease in saliva flow, can be a side effect of many drugs, which, in turn, can lead to the development of taste disturbances such as dysgeusia. [36] Patients can lessen the effects of xerostomia with breath mints, sugarless gum, or lozenges, or physicians can increase saliva flow with artificial saliva or oral pilocarpine . [36] Artificial saliva mimics the characteristics of natural saliva by lubricating and protecting the mouth but does not provide any digestive or enzymatic benefits.

Dentures provide a relative acidic, moist and anaerobic environment because the mucosa covered by the denture is sheltered from oxygen and saliva. [28] Loose, poorly fitting dentures may also cause minor trauma to the mucosa, [4] which is thought to increase the permeability of the mucosa and increase the ability of C. albicans to invade the tissues. [28] [29] These conditions all favor the growth of C. albicans . ... For example, iron deficiency anemia is thought to cause depressed cell-mediated immunity. [28] Some sources state that deficiencies of vitamin A or pyridoxine are also linked. [17] There is limited evidence that a diet high in carbohydrates predisposes to oral candidiasis. [9] In vitro and studies show that Candidal growth, adhesion and biofilm formation is enhanced by the presence of carbohydrates such as glucose , galactose and sucrose . [28] Smoking [ edit ] Smoking , especially heavy smoking, is an important predisposing factor but the reasons for this relationship are unknown. One hypothesis is that cigarette smoke contains nutritional factors for C. albicans , or that local epithelial alterations occur that facilitate colonization of candida species. [28] Antibiotics [ edit ] Broad-spectrum antibiotics (e.g. tetracycline ) eliminate the competing bacteria and disrupt the normally balanced ecology of oral microorganisms, [5] [6] which can cause antibiotic-induced candidiasis. [3] Other factors [ edit ] Several other factors can contribute to infection, including endocrine disorders (e.g. diabetes when poorly controlled), [30] and/or the presence of certain other mucosal lesions, especially those that cause hyperkeratosis and/or dysplasia [4] (e.g. lichen planus ). ...

Overview Oral thrush — also called oral candidiasis (kan-dih-DIE-uh-sis) — is a condition in which the fungus Candida albicans accumulates on the lining of your mouth. Candida is a normal organism in your mouth, but sometimes it can overgrow and cause symptoms. Oral thrush causes creamy white lesions, usually on your tongue or inner cheeks. Sometimes oral thrush may spread to the roof of your mouth, your gums or tonsils, or the back of your throat. Although oral thrush can affect anyone, it's more likely to occur in babies and older adults because they have reduced immunity; in other people with suppressed immune systems or certain health conditions; or people who take certain medications.

A second symptom could be negative symptoms, or severely disorganized or catatonic behavior. [28] Only two symptoms are required for a diagnosis of schizophrenia, resulting in different presentations for the same disorder. [28] In practice, agreement between the two systems is high. [29] The DSM-5 criteria puts more emphasis on social or occupational dysfunction than the ICD-10. [30] The ICD-10, on the other hand, puts more emphasis on first-rank symptoms. [31] [32] The current proposal for the ICD-11 criteria for schizophrenia recommends adding self-disorder as a symptom. [33] First rank symptoms [ edit ] First-rank symptoms are psychotic symptoms that are particularly characteristic of schizophrenia, which were put forward by Kurt Schneider in 1959. [34] Their reliability for the diagnosis of schizophrenia has been questioned since then. [35] A 2015 systematic review investigated the diagnostic accuracy of first rank symptoms: First rank symptoms for schizophrenia [36] Summary These studies were of limited quality. ... DSM-5 [ edit ] The definition of schizophrenia remained essentially the same as that specified by the 2000 version of DSM (DSM-IV-TR), but DSM-5 makes a number of changes: [28] Subtype classifications were removed. [30] Catatonia is no longer so strongly associated with schizophrenia. [37] In describing a person's schizophrenia, it is recommended that a better distinction be made between the current state of the condition and its historical progress, to achieve a clearer overall characterization. [30] Special treatment of Schneider's first-rank symptoms is no longer recommended. [30] Schizoaffective disorder is better defined to demarcate it more cleanly from schizophrenia. [30] An assessment covering eight domains of psychopathology – including reality distortion, negative symptoms, thought and action disorganization, cognition impairment, catatonia, and symptoms similar to those found in certain mood disorders, such as whether hallucination or mania is experienced – is recommended to help clinical decision-making. [38] The same criteria are used to diagnose children and adults. [9] [10] Diagnosis is based on reports by parents or caretakers, teachers, school officials, and others close to the child. ...

Overview Childhood schizophrenia is an uncommon but severe mental disorder in which children and teenagers interpret reality abnormally. Schizophrenia involves a range of problems with thinking (cognitive), behavior or emotions. It may result in some combination of hallucinations, delusions, and extremely disordered thinking and behavior that impairs your child's ability to function. Childhood schizophrenia is essentially the same as schizophrenia in adults, but it starts early in life — generally in the teenage years — and has a profound impact on a child's behavior and development. With childhood schizophrenia, the early age of onset presents special challenges for diagnosis, treatment, education, and emotional and social development.
One hypothesis for vulnerability to pre-eclampsia is the maternal-fetal conflict between the maternal organism and fetus. [28] After the first trimester trophoblasts enter the spiral arteries of the mother to alter the spiral arteries and thereby gain more access to maternal nutrients. [28] Occasionally there is impaired trophoblast invasion that results in inadequate alterations to the uterine spiral arteries. [28] It is hypothesized that the developing embryo releases biochemical signals that result in the woman developing hypertension and pre-eclampsia so that the fetus can benefit from a greater amount of maternal circulation of nutrients due to increased blood flow to the impaired placenta. [28] This results in a conflict between maternal and fetal fitness and survival because the fetus is invested in only its survival and fitness while the mother is invested in this and subsequent pregnancies. [28] Another evolutionary hypothesis for vulnerability to pre-eclampsia is the idea of ensuring pair-bonding between the mother and father and paternal investment in the fetus. [29] Researchers posit that pre-eclampsia is an adaptation for the mother to terminate investment in a fetus that might have an unavailable father, as determined by repeated semen exposure of the father to the mother. [29] Various studies have shown that women who frequently had exposure to partners' semen before conception had a reduced risk of pre-eclampsia. [29] Also, subsequent pregnancies by the same father had a reduced risk of pre-eclampsia while subsequent pregnancies by a different father had a higher risk of developing pre-eclampsia. [29] In normal early embryonic development, the outer epithelial layer contains cytotrophoblast cells, a stem cell type found in the trophoblast that later differentiates into the fetal placenta.
Preeclampsia is a hypertensive disorder of pregnancy that is characterized by new-onset hypertension with proteinuria presenting after 20 weeks of gestation, and depending on mild or severe forms may initially present with severe headache, visual disturbances, and hyperreflexia.
For a general phenotypic description and a discussion of genetic heterogeneity of preeclampsia, see PEE1 (189800). Mapping Hypothesizing that the genetic background of preeclampsia might show reduced heterogeneity in a founder population such as that of the Kainuu province in central eastern Finland, Laivuori et al. (2003) performed a genomewide scan in 15 multiplex families in that area. They found 2 loci that exceeded the threshold for significant linkage: 2p25 (PEE2), at 21.70 cM, and 9p13 (PEE3; 609403), at 38.90 cM. They concluded that the susceptibility locus on 2p25 was clearly different from the locus (PEE1) at 2p13 found in the Icelandic study of Arngrimsson et al. (1999).
A number sign (#) is used with this entry because of evidence that preeclampsia/eclampsia-4 can be caused by heterozygous mutation in the STOX1 gene (609397) on chromosome 10q22. For a phenotypic description and a discussion of genetic heterogeneity of preeclampsia/eclampsia, see PEE1 (189800). Mapping Lachmeijer et al. (2001) performed a genome scan using 293 polymorphic markers in 67 Dutch sib-pair families affected by preeclampsia, eclampsia, or HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets). Analysis in 38 preeclampsia families showed suggestive evidence for linkage on chromosome 22q at 32.4 cM (lod score of 2.41) and on chromosome 10q at 93.9 cM (lod score of 2.38). By affected sib-pair linkage analysis of 24 families with preeclampsia, Oudejans et al. (2004) confirmed a susceptibility locus on chromosome 10q22.1 in Dutch females, obtaining a multipoint nonparametric linkage score of 3.6 near marker D10S1432.

Inheritance Humphries (1960) presented a systematic study of hypertensive toxemia of pregnancy in mother-daughter pairs delivered at The Johns Hopkins Hospital. Toxemia occurred in 28% of daughters of women who had toxemia in the pregnancy in which they were delivered as compared with 13% in a comparison group.
A number sign (#) is used with this entry because of evidence that susceptibility to preeclampsia-5 (PEE5) is associated with heterozygous mutation in the CORIN gene (605236) on chromosome 4p12. For a phenotypic description and a discussion of genetic heterogeneity of preeclampsia/eclampsia, see PEE1 (189800). Molecular Genetics Cui et al. (2012) identified 2 missense mutations in the CORIN gene in women with preeclampsia. One, a lys317-to-glu substitution in low density lipoprotein receptor repeat-2 region (605236.0001), was found in 1 woman; the other, a ser472-to-gly substitution in the frizzled-2 domain (605236.0002), was found in 2 women from the same family. Neither mutation affected CORIN expression in HEK293 cells, but both markedly reduced CORIN activity in processing pro-atrial natriuretic peptide (ANP; 108780).
Overview Preeclampsia is a complication of pregnancy. With preeclampsia, you might have high blood pressure, high levels of protein in urine that indicate kidney damage (proteinuria), or other signs of organ damage. Preeclampsia usually begins after 20 weeks of pregnancy in women whose blood pressure had previously been in the standard range. Left untreated, preeclampsia can lead to serious — even fatal — complications for both the mother and baby. Early delivery of the baby is often recommended. The timing of delivery depends on how severe the preeclampsia is and how many weeks pregnant you are. Before delivery, preeclampsia treatment includes careful monitoring and medications to lower blood pressure and manage complications.
The pathogenesis of leptospirosis remains poorly understood despite research efforts. [7] [28] The bacteria enter the human body through either breaches in the skin or the mucous membrane, then into the bloodstream. ... They also bind to several human proteins such as complement proteins, thrombin , fibrinogen , and plasminogen using surface leptospiral immunoglobulin-like (Lig) proteins such as LigB and LipL32, whose genes are found in all pathogenic species.

Leptospirosis is an anthropozoonosis caused by spiral-shaped bacteria belonging to the genus Leptospira. Leptospirosis is a widespread zoonosis with a worldwide distribution and has emerged as a major public health problem in developing countries in South-East Asia and South America. Epidemiology Estimations from the World Health Organization (WHO) indicate that over 500,000 cases of severe leptospirosis are thought to occur each year, with a mortality rate of over 10%. However, the incidence in Europe is much lower with less than 500 cases being diagnosed per year in each European country. Clinical description Initial signs of infection include fever associated with shivering and pain (myalgia, headaches and abdominal pain).

There is a mean-level change in the Big Five traits from age 10 to 65. [28] The trends seen in adulthood are different from trends seen in childhood and adolescence . Some research suggests that during adolescence rank-order change does occur and therefore personality is relatively unstable. [29] Gender differences are also shown before adulthood. [28] Conscientiousness drops from late childhood to adolescence, but then picks back up from adolescence into adulthood. ... These trends seen in adulthood are different from trends seen in childhood and adolescence. [28] Cross-cultural research shows that German, British, Czech, and Turkish people show similar trends of these personality traits. [30] Similar trends seem to exist in other countries. [31] The Big Five personality traits can also be broken down into facets . ... However, it is important to look at change in facets over a lifetime separate from just the change in traits because different facets of the same trait show different trends. [32] [28] For example, openness to values decreases substantially with age, while openness to aesthetics is more stable. [32] Neuroticism can be broken into the two facets of anxiety and depression. ... For males, depression tends to show an increase from childhood to early adulthood and then shows a slight decrease through middle age. [28] Late life changes [ edit ] Although there is debate surrounding whether or not personality can change in the late stages of life, more evidence is being discovered about how the environmental factors affect people of all ages.
The average age at death of affected persons in the second generation was 72, in the third generation 63, in the fourth 42, and in the fifth 28. Follow-up of this family (Gardner and Turner, 1940; Young et al., 1970) revealed no evidence of the systemic manifestations of neurofibromatosis I (NF1; 162200), also known as von Recklinghausen disease. ... Molecular genetic analysis of the NF2 gene was performed in all 45 patients and on 28 tumor samples. No pathogenic NF2 mutations were identified in any of the blood samples. NF2 point mutations were identified in 21 of 28 (75%) tumor samples and LOH in 21 of 28 (75%) tumor samples. Overlap, i.e., both mutational hits, were identified in 18 of 28 (65%) tumor samples. They observed 1 multilobular tumor in which 1 (presumably first hit) mutation was confirmed which was common to different foci of the tumor, while the second mutational event differed between foci. ... Ruttledge et al. (1996) reported that when individuals harboring protein-truncating mutations are compared with patients having single codon alterations, a significant correlation (p less than 0.001) with clinical outcome is observed. They noted that 24 of 28 patients with mutations that cause premature termination of the NF2 protein presented with severe phenotypes.
Type of neurofibromatosis disease Neurofibromatosis type II Other names multiple inherited schwannomas, meningiomas, and ependymomas (MISME syndrome)) Micrograph of a schwannoma , a tumor seen in neurofibromatosis type II. HPS stain . Specialty Medical genetics , neurology Neurofibromatosis type II (also known as MISME syndrome – multiple inherited schwannomas, meningiomas, and ependymomas) is a genetic condition which may be inherited or may arise spontaneously. The main manifestation of the condition is the development of bilateral benign brain tumors in the nerve sheath of the cranial nerve VIII , which is the "auditory-vestibular nerve" that transmits sensory information from the inner ear to the brain . Besides, other benign brain and spinal tumors occur. Symptoms depend on the presence, localisation and growth of the tumor(s). Many people with this condition also experience visual problems. Neurofibromatosis type II (NF2 or NF II) is caused by mutations of the "Merlin" gene , [1] which seems to influence the form and movement of cells .
Neurofibromatosis type 2 (NF2) is a tumor-prone disorder characterized by the development of multiple schwannomas and meningiomas. Epidemiology Prevalence (initially estimated at 1: 200,000) is around 1 in 60,000. Clinical description Affected individuals inevitably develop schwannomas, typically affecting both vestibular nerves and leading to hearing loss and deafness. The majority of patients present with hearing loss, which is usually unilateral at onset and may be accompanied or preceded by tinnitus. Vestibular schwannomas may also cause dizziness or imbalance as a first symptom.
Summary Clinical characteristics. Neurofibromatosis 2 (NF2) is characterized by bilateral vestibular schwannomas with associated symptoms of tinnitus, hearing loss, and balance dysfunction. The average age of onset is 18 to 24 years. Almost all affected individuals develop bilateral vestibular schwannomas by age 30 years. Affected individuals may also develop schwannomas of other cranial and peripheral nerves, meningiomas, ependymomas, and, very rarely, astrocytomas. Because NF2 is considered an adult-onset disease, it may be underrecognized in children, in whom skin tumors and ocular findings (retinal hamartoma, thickened optic nerves, cortical wedge cataracts, third cranial nerve palsy) may be the first manifestations. Mononeuropathy that occurs in childhood is an increasingly recognized finding; it frequently presents as a persistent facial palsy or hand/foot drop.
Neurofibromatosis type 2 (NF2) is a disorder characterized by the growth of noncancerous tumors of the nervous system. Childhood symptoms include skin growths and eye findings. Almost all people with NF2 develop vestibular schwannomas affecting both ears by age 30. Other tumors of the central nervous system (the brain and spinal cord), skin and eye are also common. The signs and symptoms vary from person to person. The severity depends on the size, location, and number of tumors. NF2 is caused by changes (mutations) in the NF2 gene and is inherited in an autosomal dominant manner.
Neurofibromatosis type 2 is a disorder characterized by the growth of noncancerous tumors in the nervous system. The most common tumors associated with neurofibromatosis type 2 are called vestibular schwannomas or acoustic neuromas. These growths develop along the nerve that carries information from the inner ear to the brain (the auditory nerve). Tumors that occur on other nerves are also commonly found with this condition. The signs and symptoms of neurofibromatosis type 2 usually appear during adolescence or in a person's early twenties, although they can begin at any age.
Other scientific findings [ edit ] A study conducted in 2016 used primary metabolite profiling through a combination of liquid chromatography and mass spectrometry to identify possible biomarkers for anxiety-related behavior. [27] Primary metabolites are directly involved in more "natural" processes, such as reproduction and development, [28] so abnormal differences could result in differences of mental development. ...

In others, such as Monotonic Dystrophy Type 1, the pathology is caused by a change in protein expression or function mediated through changes in the messenger RNA produced by the expression of the affected gene. [1] In yet others, the pathology is caused by toxic assemblies of RNA in the nuclei of cells.

A rare multiple congenital anomalies syndrome characterized by muscular pseudohypertrophy, short stature, reduced joint mobility, brachydactyly, mixed hearing loss and intellectual disability of variable severity. Facial dysmorphism with short palpebral fissures, short philtrum, thin lips, maxillary hypoplasia and prognathism is present. Thick skin has been observed.
Summary Clinical characteristics. Myhre syndrome is a connective tissue disorder with multisystem involvement, progressive and proliferative fibrosis that may occur spontaneously or following trauma or surgery, mild-to-moderate intellectual disability, and in some instances, autistic-like behaviors. Organ systems primarily involved include: cardiovascular (congenital heart defects, long- and short-segment stenosis of the aorta and peripheral arteries, pericardial effusion, constrictive pericarditis, restrictive cardiomyopathy, and hypertension); respiratory (choanal stenosis, laryngotracheal narrowing, obstructive airway disease, or restrictive pulmonary disease), gastrointestinal (pyloric stenosis, duodenal strictures, severe constipation); and skin (thickened particularly on the hands and extensor surfaces). Additional findings include distinctive craniofacial features and skeletal involvement (intrauterine growth restriction, short stature, limited joint range of motion). To date, 55 individuals with molecularly confirmed Myhre syndrome have been reported. Diagnosis/testing. The diagnosis of Myhre syndrome is established by detecting a de novo SMAD4 heterozygous pathogenic variant in a proband with characteristic clinical findings.
Myhre syndrome is a rare condition that affects connective tissue . Connective tissue provides strength and flexibility to structures throughout the body. Myhre syndrome has a variety of signs and symptoms that affect many parts of the body, though not everyone has all the possible features. The features of the condition can range in severity, and some features become more apparent with age. Common signs and symptoms of Myhre syndrome include short stature, skeletal abnormalities, limited joint mobility, characteristic facial features, intellectual and behavioral problems, hearing loss, a tendency for the buildup of scar tissue (fibrosis) in the skin and internal organs, and heart and lung abnormalities. Growth is reduced in most people with Myhre syndrome, beginning before birth and continuing through adolescence.
Myhre syndrome Other names Facial dysmorphism-intellectual disability-short stature-hearing loss syndrome Myhre syndrome is inherited in an autosomal dominant manner [1] Specialty Medical genetics Myhre syndrome is a rare genetic disorder inherited in an autosomal dominant fashion. It is caused by mutation in SMAD4 gene. Contents 1 Signs and symptoms 2 Genetics 3 Diagnosis 4 Treatment 5 History 6 References 7 External links Signs and symptoms [ edit ] The clinical presentation is variable but includes [ citation needed ] developmental and growth delay athletic muscular built skeletal anomalies joint stiffness characteristic facial appearance deafness variable cognitive deficits tracheal stenosis aortic stenosis pyloric stenosis The facial abnormalities include: blepharophimosis (an abnormally narrow gap between the upper and lower eyelids) maxillary hypoplasia (underdevelopment of the upper jaw) prognathism (prominent lower jaw) The skeletal abnormalities include: short stature square body shape broad ribs iliac hypoplasia brachydactyly flattened vertebrae thickened calvaria Congenital heart disease and undescended testes have also been reported in association with this syndrome. Genetics [ edit ] Myhre syndrome is due to mutations in the SMAD4 gene. [2] This gene encodes a protein - transducer mediating transforming growth factor beta. Some researchers believe that the SMAD4 gene mutations that cause Myhre syndrome impair the ability of the SMAD4 protein to attach (bind) properly with the other proteins involved in the signaling pathway. Other studies have suggested that these mutations result in an abnormally stable SMAD4 protein that remains active in the cell longer.
Myhre syndrome is a rare, connective tissue disorder that affects many parts of the body. Signs and symptoms include fibrosis (thickening and scarring of connective tissue), intellectual disability, distinctive facial features, skeletal abnormalities, and/or various birth defects. The syndrome may affect the structure or function of the heart, the respiratory system, the gastrointestinal system, and the skin. Myhre syndrome is caused by a mutation in the SMAD4 gene. The mutation typically occurs for the first time in an affected person. To date, no reported cases have been inherited from a parent. Inheritance is autosomal dominant, but there are no reported cases of a person with Myhre syndrome having children.
