In a cohort of 58 Spanish patients diagnosed with Usher syndrome (see 276900), Fuster-Garcia et al. (2018) performed targeted exome sequencing for variation in 10 known Usher-associated genes and 4 candidate genes, and identified a woman (RP1973) with hearing loss and mild retinal degeneration involving the macula who was compound heterozygous for nonsense mutations in the CEP250 gene: K1113X (609689.0004) and R1336X (609689.0005).
Clinical Features Mahloudji (1963) described a rare hereditary syndrome of spastic ataxia, closely resembling disseminated sclerosis (126200), in 18 persons in an Iranian family.
A rare, genetic, autosomal dominant spastic ataxia disorder characterized by lower-limb spasticity and ataxia in the form of head jerks, ocular movement abnormalities, dysarthria, dysphagia and gait disturbances.
A few of the exacerbations were accompanied by respiratory insufficiency requiring artificial ventilation, and 1 patient developed an acute episode of hemolytic-uremic syndrome during plasmapheresis that resolved.
Primary CD59 deficiency is a rare, genetic, hematologic and neurologic disease characterized by chronic, Coombs-negative hemolysis associated with early-onset, relapsing, immune-mediated, inflammatory, axonal or demyelinating, sensory-motor, peripheral polyneuropathy and isolated or recurrent cerebrovascular events (in anterior or posterior circulation).
One woman had recurrent episodes of palpitations and syncope at 32 years of age and was diagnosed with Wolff-Parkinson-White syndrome (194200); an echocardiogram showed borderline hypertrophy which enlarged significantly over the next 7 years, from 12 mm to 19 mm.
Exclusion Studies In 2 Pakistani sisters with a form of SEMD and mental retardation, Genevieve et al. (2005) excluded mutation in the DYM gene (607461), which is responsible for Dyggve-Melchior-Clausen syndrome (223800), and in the PAPSS2 gene (603005), which is responsible for the Pakistani type of SEMD (612847).
Spondyloepimetaphyseal dysplasia, Geneviève type is a rare primary bone dysplasia characterized by severe developmental delay and skeletal dysplasia (including short stature, premature carpal ossification, platyspondyly, longitudinal metaphyseal striations, and small epiphyses), as well as moderate to severe intellectual disability and facial dysmorphism, including prominent forehead, mild synophrys, depressed nasal bridge, prominent bulbous nasal tip and full lips.
Affected members showed a relatively mild ataxia syndrome with cognitive impairment, poor performance on the Wisconsin Card Sorting Test, myoclonus, and a postural irregular tremor of low frequency.
Spinocerebellar ataxia type 19 (SCA19) is a very rare subtype of type I autosomal dominant cerebellar ataxia (ADCA type I; see this term). It is characterized by mild cerebellar ataxia, cognitive impairment, low scores on the Wisconsin Card Sorting Test measuring executive function, myoclonus, and postural tremor. Epidemiology Prevalence is unknown. Only 12 cases in a 5-generation Dutch family have been reported to date. Clinical description SCA19 presents in the 3rd decade of life with symptomatic disease onset ranging from 10 to 46 years. Onset symptoms of SCA22 (see this term) overlap significantly with those of SCA19 but with a more narrow age range of 35 to 46 years.
Although primary shunt hyperbilirubinemia is clinically similar to Gilbert syndrome (143500), affected individuals do not have impaired activity of UDP-glucuronosyltransferase (UGT1A1; 191740).
Review of Reticulate Pigment Disorders Muller et al. (2012) reviewed the spectrum of reticulate pigment disorders of the skin, tabulating all reported cases of patients with Dowling-Degos disease (see DDD1; 179850), reticulate acropigmentation of Kitamura (RAK; 615537), reticulate acropigmentation of Dohi (RAD), Galli-Galli disease (GGD), and Haber syndrome (HS). Of 82 cases, 26 (31.7%) were clinically diagnosed as DDD, 13 (15.9%) as RAD, 11 (13.4%) as GGD, 8 (9.8%) as RAK, and 8 (9.8%) as HS; in addition, 16 (19.5%) of the cases showed overlap between DDD and RAK.
A rare genodermatosis characterised by the presence of hyperpigmented and hypopigmented macules, principally located on the extremities and limbs. Clinical description The first manifestations of the disease generally appear during early childhood. Etiology A mutation has been identified in the double-stranded RNA-specific adenosine deaminase ( ADAR ) gene. Genetic counseling Transmission is autosomal dominant.
Dyschromatosis symmetrica hereditaria Other names Acropigmentation of Dohi [1] Dyschromatosis symmetrica hereditaria is inherited in an autosomal dominant manner Dyschromatosis symmetrica hereditaria (also known as " reticulate acropigmentation of Dohi ", and " symmetrical dyschromatosis of the extremities ") is a rare autosomally inherited dermatosis. It is characterized by progressively pigmented and depigmented macules , often mixed in a reticulate pattern, concentrated on the dorsal extremities. [2] : 855 It presents primarily in the Japanese , but has also been found to affect individuals from Europe , India and the Caribbean . Contents 1 Genetics 2 Diagnosis 3 Treatment 4 See also 5 References 6 External links Genetics [ edit ] This disease is caused by mutation in the double stranded RNA specific adenosine deaminase ( ADAR1 ) gene.

Assmann et al. (1997) raised the question of whether this was 1 disorder or 2 independent recessive disorders and whether this might represent a hitherto undescribed contiguous gene syndrome. Hamajima et al. (1998) stated that 9 cases of dihydropyrimidinuria had been reported.
The uterus might be simultaneously reduced in volume, and other abnormalities might be concomitantly present. [9] Prognosis [ edit ] T-shaped uterus sufferers can bear children, however they carry a greater risk of complications, such as miscarriages, reduced fertility and preterm births, both before and after any treatment. [10] [11] The current surgical procedure to treat this malformation, termed a hysteroscopic correction or metroplasty , is undertaken by performing a lateral incision of the uterine walls, and can return the organ to a normal morphology, while improving the patient's former reproductive performance. [4] [10] [12] It is considered a low-risk procedure, and can also improve term delivery rate by up to 10-fold, as long as the endometrium is considered to be in good condition. [13] [14] [15] However, risks after the procedure include placenta accreta , Asherman's syndrome and severe haemorrhage .

A rare congenital disorder of glycosylation characterized by neonatal onset of global developmental delay, hypotonia, failure to thrive, hematological/immunological abnormalities, recurrent infections, liver involvement (with hepatosplenomegaly, cholestasis, fibrosis, or cirrhosis), and enteropathy. Additional reported manifestations include dysmorphic craniofacial features (such as microcephaly, broad palpebral fissures, and retrognathia), hypohidrosis, hyperkeratosis, and cardiac and musculoskeletal anomalies. Brain imaging may show hypoplastic corpus callosum, cerebral and cerebellar atrophy, and enlarged ventricles.
Nearly all the featured stories involved women who continued to have their period as usual throughout their pregnancy, while some cited not having regular periods due to polycystic ovarian syndrome (PCOS), or other conditions that are associated with infertility.
Embryonal carcinoma is a type of testicular cancer , which is cancer that starts in the testicles, the male reproductive glands located in the scrotum. It most often develops in young and middle-aged men. It tends to grow rapidly and spread outside the testicle. Embryonal carcinomas are classified as nonseminoma germ cell tumors. Most testicular cancers grow from germ cells, the cells that make sperm. Germ cell tumors are broadly divided into seminomas and nonseminomas because each type has a different prognosis and treatment regimen. Nonseminomas, which are more common, tend to grow more quickly than seminomas.
