Deafness, which was accompanied by vestibular hypofunction, lentigines even in unexposed areas, optic nerve dysplasia, and dominant inheritance distinguished this form of ocular albinism. (In the LEOPARD syndrome (151100) vestibular function is normal.) Bard (1978) described a kindred that was atypical of Waardenburg syndrome (see 193510) in several ways. Although the nasal root was prominent, one affected person had dystopia of the inner canthi or lower puncta. ... Lewis (1989) expressed the opinion that the family reported by Bard (1978) as an instance of Waardenburg syndrome in fact had this disorder. Lewis (1989) had also been told of 2 other small families with the syndrome. Goldberg (1966) described a Waardenburg syndrome family with apparent ocular albinism. ... One individual with a prominent white forelock, characteristic of Waardenburg syndrome, was pictured. Molecular Genetics Studying the family reported by Bard (1978), Morell et al. (1997) demonstrated apparent digenic inheritance resulting from a combination of heterozygosity for a 1-bp deletion in exon 8 of the MITF gene (156845.0005) and homozygosity or heterozygosity for the R402Q polymorphism of the tyrosinase gene (TYR; 606933.0009), a functionally significant polymorphism that is associated with moderately reduced tyrosinase catalytic activity, and also heterozygous for the 1-bp deletion in MITF.
In a large Afrikaner kindred, Winship et al. (1984) observed 7 males in 4 sibships in 3 generations with the combination of typical ocular albinism and sensorineural deafness of late onset. Typicality of the ocular albinism was supported by numerous macromelanosomes demonstrated on skin biopsy of both affected males and carriers. Deafness was moderately severe by late middle age. The pedigree pattern was consistent with X-linked recessive inheritance. In the same large South African family, Winship et al. (1993) found tight linkage to the DXS452 locus at Xp22.3 using 25 informative meioses, with a maximum lod score of 7.1 at a recombination fraction of 0.0. Since OA1 (300500) has been mapped to Xp22.3-p22.2, Winship et al. (1993) suggested that OA1 and OASD may be allelic variants or that they may be due to contiguous gene defects.
Ocular albinism with late-onset sensorineural deafness is a rare, X-linked inherited subtype of ocular albinism characterized by severe visual impairment, translucent pale-blue irises, a reduction in the retinal pigment and moderately severe deafness with onset ranging from adolescence to fourth or fifth decade of life.
Clinical Features Braddock et al. (1993) reported 4 cases of sagittal craniosynostosis and the Dandy-Walker malformation (posterior fossa cyst, hypoplasia of the cerebellar vermis and often hydrocephalus) and suggested that they represented an autosomal dominant multiple malformation syndrome distinct from other disorders in which either craniosynostosis or the Dandy-Walker malformation is present. ... (Cohen (1993) referred to this as Jones syndrome. Not unexpectedly, at least one other disorder had been referred to as Jones syndrome (135550).) ... Mapping Vincent et al. (1994) described a contiguous gene syndrome resulting from deletion of 8q12.2-q21.2 (600257) and characterized by a combination of hydrocephalus with branchiootorenal (BOR) syndrome (113650), Duane syndrome (126800), and aplasia of the trapezius muscle.
Craniosynostosis, Dandy-Walker malformation and hydrocephalus is a malformation disorder characterized by sagittal craniosynostosis (see this term), Dandy-Walker malformation, hydrocephalus, craniofacial dysmorphism (including dolichocephaly, hypertelorism, micrognathia, positional ear deformity) and variable developmental delay. The inheritance pattern appears to be autosomal dominant.
Ectopia lentis can also be classified as syndromic, when it is part of a syndrome that affects multiple parts of the body. Ectopia lentis is a common feature of genetic syndromes such as Marfan syndrome and Weill-Marchesani syndrome. ... In Denmark, an estimated 6.4 per 100,000 individuals have ectopia lentis, but a large proportion of these cases (about 75 percent) are syndromic. Causes Mutations in the FBN1 or ADAMTSL4 gene cause isolated ectopia lentis.
Maternal diabetes is a major risk factor for developing this syndrome, which is up to 200 fold more frequent than in the general population. ... The etiology seems to be multifactorial as maternal diabetes, vascular hypoperfusion, and genetic predisposition (for example mutation in VANGL1 gene) can lead to the syndrome. Diagnostic methods Diagnosis is based on antenatal ultrasound examination in the first trimester of pregnancy in the most severe cases. ... CRS has also been associated with the VACTERL syndrome (see this term). The Currarino syndrome (see this term) is a form of caudal regression syndrome characterized by the classic triad of presacral mass, sacral bone defect and anorectal malformation in which an autosomal dominant inheritance has been described with mutation or deletion of the HLXB9 gene. ... Depending on the severity of the syndrome, orthopedic interventions may also be required.
Caudal regression sequence (CRS) affects the development of the lower (caudal) half of the body. It can impact the development of the lower back, spinal cord, and lower limbs. The kidneys, bladder, digestive tract, and genitalia may also be affected. CRS occurs during fetal development and is present at birth. The features and severity vary from person to person. In some cases, CRS is severe and can be life-threatening. In other cases, people with CRS may have problems with bowel and bladder control and be unable to walk.
A rare, genetic intellectual disability syndrome characterized by severe global developmental delay with intellectual disability, microcephaly, growth retardation, ocular defects such as congenital cataract, and nevus flammeus simplex on the forehead. ... Polymicrogyria has recently been reported as a distinctive neuro-radiological finding. Etiology The syndrome is caused by homozygous variants in the MED25 gene (19q13.33), coding for a component of the mediator complex. ... Differential diagnosis Differential diagnosis include other genetic syndromes characterized by intellectual disability accompanied by eye and brain abnormalities.
A number sign (#) is used with this entry because of evidence that Basel-Vanagaite-Smirin-Yosef syndrome (BVSYS) is caused by homozygous mutation in the MED25 gene (610197) on chromosome 19q13. Description Basel-Vanagaite-Smirin-Yosef syndrome is an autosomal recessive multiple congenital anomaly disorder characterized by severely delayed psychomotor development resulting in mental retardation, as well as variable eye, brain, cardiac, and palatal abnormalities (summary by Basel-Vanagaite et al., 2015). Clinical Features Basel-Vanagaite et al. (2015) reported 7 children from 4 unrelated families living in the same small village in Israel with a severe syndromic neurodevelopmental disorder. All had severely delayed psychomotor development apparent from infancy and variable eye abnormalities, including ptosis, microcornea, and congenital cataracts.
Psychological disorder proposed by professor Makoto Natsume A waitress at a restaurant is expected to exhibit positivity, such as smiling and expressing positive emotion towards customers Smile mask syndrome ( Japanese : スマイル仮面症候群 , Hepburn : sumairu kamen shōkōgun ) , abbreviated SMS , is a psychological disorder proposed by professor Makoto Natsume of Osaka Shoin Women's University , in which subjects develop depression and physical illness as a result of prolonged, unnatural smiling. [1] Natsume proposed the disorder after counselling students from the university in his practice and noticing that a number of students had spent so much time faking their smiles that they were unaware that they were smiling even while relating stressful or upsetting experiences to him. ... He relates examples of patients saying that they felt their smile had a large effect on whether they were hired or not, and that their superiors had stressed the effect that good smiles had on customers. [2] According to Natsume, this atmosphere sometimes causes women to smile unnaturally for so long that they start to suppress their real emotions and become depressed. [3] Japanese author Tomomi Fujiwara notes that the demand for a common smile in the workplace emerged in Japan around the 1980s, and blames the cultural changes wrought by the Tokyo Disneyland , opened in 1983, for popularizing the demand for an obligatory smile in the workplace. [3] The smile mask syndrome has also been identified in Korea. [4] Korean writer Bae Woo-ri noted that smiling gives one a competitive advantage over the others, and has become a necessary attribute of many employees, just like a "neat uniform". [4] Yoon-Do-rahm, a psychology counselor, compared the current society, which is full of smile-masks, to a clown show; both are characterized by plentiful, yet empty and fake, smiles. [4] Smile mask syndrome can cause physical problems as well as mental ones.

Description Thauvin-Robinet-Faivre syndrome is an autosomal recessive disorder characterized by generalized overgrowth, mainly of height, and mildly delayed psychomotor development with mild or severe learning difficulties. ... Clinical Features Thauvin-Robinet et al. (2016) reported a 23-year-old man, born of consanguineous North African parents, with an overgrowth syndrome and severe learning disabilities. ... Akawi et al. (2016) reported 3 sibs, born of consanguineous Arab parents, with an overgrowth syndrome associated with mildly delayed developmental milestones and intellectual disability.
Description FATCO syndrome comprises fibular aplasia, tibial campomelia, and oligosyndactyly (Courtens et al., 2005). ... Although the femur and ulna were reportedly normal, Capece et al. (1994) diagnosed the femur-fibula-ulnar syndrome (228200) in that patient. Courtens et al. (2005) also referred to 2 unrelated Brazilian boys reported by Huber et al. (2003) who had bowed and short tibia, bilateral absence of the fibulae, and oligodactyly of the hands and feet. Although the femora and pelvic bones were reportedly normal, Huber et al. (2003) concluded that the Brazilian boys had Fuhrmann syndrome (228930). Courtens et al. (2005) stated that the common findings in these 5 patients included fibular agenesis, tibial campomelia, and oligosyndactyly, and proposed the acronym 'FATCO' for this condition.
A number sign (#) is used with this entry because of evidence that lethal congenital contracture syndrome-8 (LCCS8) is caused by homozygous mutation in the ADCY6 gene (600294) on chromosome 12q13. ... Description Lethal congenital contracture syndrome-8, an axoglial form of arthrogryposis multiplex congenita, is characterized by congenital distal joint contractures, reduced fetal movements, and severe motor paralysis leading to death early in the neonatal period (Laquerriere et al., 2014). For a general phenotypic description and a discussion of genetic heterogeneity of lethal congenital contracture syndrome, see LCCS1 (253310). Clinical Features Laquerriere et al. (2014) reported 2 sibs from a consanguineous family (A649) who were diagnosed with distal arthrogryposis multiplex congenita at 32 weeks' gestation by fetal ultrasound.
A rare, genetic, neurologic disease characterized by primary hyperaldosteronism presenting with early-onset, severe hypertension, hypokalemia and neurological manifestations (including seizures, severe hypotonia, spasticity, cerebral palsy and profound developmental delay/intellectual disability).
A number sign (#) is used with this entry because of evidence that primary aldosteronism with seizures and neurologic abnormalities (PASNA) is caused by heterozygous mutation in the CACNA1D gene (114206) on chromosome 3p21. Clinical Features Scholl et al. (2013) studied 2 patients with primary aldosteronism and neurologic abnormalities. The first patient was a 3-year-old girl of European ancestry who was diagnosed at birth with hypertension as well as biventricular hypertrophy, ventricular septal defect, pulmonary hypertension, and second-degree atrioventricular block. Her aldosterone levels were high, with low plasma renin activity (PRA) and an elevated aldosterone/renin ratio, consistent with primary hyperaldosteronism. Her clinical course was notable for uncontrolled hypertension with hypokalemia.
A rare developmental defect during embryogenesis disorder characterized by spinal dysraphism, cleft lip and palate, limb reduction defects and anencephaly. There have been no further descriptions in the literature since 1994.
A rare, genetic, epidermal disease characterized by punctate keratoderma on palms and soles associated with irregularly shaped hypopigmented macules (typically localized on the extremities). Ectopic calcification (e.g. early-onset calcific tendinopathy, calcinosis cutis) and pachyonychia may be occasionally associated.
Cole disease is a disorder that affects the skin. People with this disorder have areas of unusually light-colored skin (hypopigmentation), typically on the arms and legs, and spots of thickened skin on the palms of the hands and the soles of the feet (punctate palmoplantar keratoderma). These skin features are present at birth or develop in the first year of life. In some cases, individuals with Cole disease develop abnormal accumulations of the mineral calcium (calcifications) in the tendons, which can cause pain during movement. Calcifications may also occur in the skin or breast tissue. Frequency Cole disease is a rare disease; its prevalence is unknown. Only a few affected families have been described in the medical literature.
A number sign (#) is used with this entry because of evidence that Cole disease (COLED) is caused by heterozygous mutation in the ENPP1 gene (173335) on chromosome 6q23. Description Cole disease is a rare autosomal dominant disorder characterized by congenital or early-onset punctate keratoderma associated with irregularly shaped hypopigmented macules, which are typically found over the arms and legs but not the trunk or acral regions. Skin biopsies of palmoplantar lesions show nonspecific changes including hyperorthokeratosis, hypergranulosis, and acanthosis. Hypopigmented areas of skin, however, reveal a reduction in melanin content in keratinocytes but not in melanocytes, as well as hyperkeratosis and a normal number of melanocytes. Ultrastructurally, melanocytes show a disproportionately large number of melanosomes in the cytoplasm and dendrites, whereas keratinocytes show a paucity of these organelles, suggestive of impaired melanosome transfer (summary by Eytan et al., 2013).
An autosomal anomaly characterized by variable clinical features, depending on the size and precise location of deleted chromosome segments. Most patients present with developmental delay, intellectual disability, growth retardation, microcephaly, clinodactyly, and dysmorphic features. Congenital heart disease and genitourinary anomalies were reported in some cases.

A number sign (#) is used with this entry because of evidence that auditory neuropathy and optic atrophy (ANOA) is caused by homozygous or compound heterozygous mutation in the FDXR gene (103270) on chromosome 17q25. Description ANOA is an autosomal recessive neurologic disorder characterized by onset of visual and hearing impairment in the first or second decades (summary by Paul et al., 2017). Clinical Features Paul et al. (2017) reported 8 patients from 4 unrelated families with sensorineural neuropathies affecting vision and hearing. The families were of various ethnicities, including Tunisian, Algerian, French, and Russian. The patients had onset of hearing loss and visual impairment in the first or second decades.
A rare genetic disease characterized by frequent infections associated with neutropenia and IgA deficiency, in combination with osteoporosis and skeletal anomalies, such as posterior spinal arch fusion defect, metacarpal subluxation, syndactyly, and camptodactyly. Reported dysmorphic features include synophrys, anteverted nostrils, and single palmar crease. There have been no further descriptions in the literature since 1972.
Clinical Features In both of female monozygotic twins, Lichtenstein (1972) described a 'new' syndrome comprising frequent infections due to a leukocyte and immune defect (neutropenia, IgA deficiency), bony abnormalities (peripheral osteoporosis) with tendency to fracture, failure of fusion of posterior spinal arches, subluxation at C1-C2 resulting in long-tract signs, metacarpal subluxation, syndactyly, and camptodactyly with ulnar deviation of the fingers and simian crease, giant cyst of the lung, and unusual facies ('carp mouth,' synophrys, anteverted nostrils).
