Medium match NON-PROGRESSIVE CEREBELLAR ATAXIA WITH INTELLECTUAL DISABILITY

Non-progressive cerebellar ataxia with intellectual deficit is a rare subtype of autosomal dominant cerebellar ataxia type 1 (ADCA type 1; see this term) characterized by the onset in infancy of cerebellar ataxia, neonatal hypotonia (in some), mild developmental delay and, in later life, intellectual disability. Less common features include dysarthria, dysmetria and dysmorphic facial features (long face, bulbous nose long philtrum, thick lower lip and pointed chin).

Andersen's syndrome (AS) is a rare disorder characterized by periodic muscle paralysis, prolongation of the QT interval with a variety of ventricular arrhythmias (leading to predisposition to sudden cardiac death) and characteristic physical features: short stature, scoliosis, low-set ears, hypertelorism, broad nasal root, micrognathia, clinodactyly, brachydactyly and syndactyly.

Medium match CORNELIA DE LANGE SYNDROME 5; CDLS5

Cornelia de Lange syndrome is a clinically heterogeneous developmental disorder characterized by malformations affecting multiple systems. Affected individuals have dysmorphic facial features, cleft palate, distal limb defects, growth retardation, and developmental delay. About 60% of patients have mutations in the NIPBL gene (OMIM ) on chromosome 5p13 (CDLS1 ), and about 4 to 6% of patients have mutations in the X-linked SMC1A gene (OMIM ) (CDLS2 ) (summary by Musio et al., 2006, Hoppman-Chaney et al., 2012).For a general phenotypic description and a discussion of genetic heterogeneity of Cornelia de Lange syndrome, see {122470}.

Medium match GROWTH DELAY DUE TO INSULIN-LIKE GROWTH FACTOR I RESISTANCE

Growth delay due to IGF-I resistance is characterised by variable intrauterine and postnatal growth retardation and elevated serum IGF-I levels. Addition features include variable degrees of intellectual deficit, microcephaly and dysmorphism (broad nasal bridge and tip, smooth philtrum, thin upper and everted lower lips, short fingers, clinodactyly, wide-set nipples and pectus excavatum).

Medium match SHORT STATURE, MICROCEPHALY, AND ENDOCRINE DYSFUNCTION; SSMED

In patients with SSMED, short stature and microcephaly are apparent at birth, and there is progressive postnatal growth failure. Endocrine dysfunction, including hypergonadotropic hypogonadism, multinodular goiter, and diabetes mellitus, is present in affected adults. Progressive ataxia has been reported in some patients, with onset ranging from the second to fifth decade of life. In addition, a few patients have developed tumors, suggesting that there may be a predisposition to tumorigenesis. In contrast to syndromes involving defects in other components of the nonhomologous end-joining (NHEJ) complex (see, e.g., {606593}), no clinically overt immunodeficiency has been observed in SSMED, although laboratory analysis has revealed lymphopenia or borderline leukopenia in some patients (Murray et al., 2015; Bee et al., 2015; de Bruin et al., 2015; Guo et al., 2015).

Medium match GM1-GANGLIOSIDOSIS, TYPE I

GM1-Gangliosidosis is an autosomal recessive lysosomal storage disease characterized by accumulation of ganglioside substrates in lysosomes. Clinically, patients show variable degrees of neurodegeneration and skeletal abnormalities. There are 3 main clinical variants categorized by severity and variable residual beta-galactosidase activity. Type I, or infantile form, shows rapid psychomotor deterioration beginning within 6 months of birth, generalized central nervous system involvement, hepatosplenomegaly, facial dysmorphism, macular cherry-red spots, skeletal dysplasia, and early death. Type II, or late-infantile/juvenile form (OMIM ), has onset between 7 months and 3 years, shows generalized central nervous system involvement with psychomotor deterioration, seizures, localized skeletal involvement, and survival into childhood. Hepatosplenomegaly and cherry-red spots are usually not present. Type III, or adult/chronic form (OMIM ), shows onset from 3 to 30 years and is characterized by localized skeletal involvement and localized central nervous system involvement, such as dystonia or gait or speech disturbance. There is an inverse correlation between disease severity and residual enzyme activity (Suzuki et al., 2001).See also Morquio B disease (OMIM ), an allelic disorder with skeletal anomalies and no neurologic involvement.The GM2-gangliosidoses include Tay-Sachs disease (OMIM ) and Sandhoff disease (OMIM ).
