Medium match WOLFRAM SYNDROME 1; WFS1

Wolfram syndrome-1 is a rare and severe autosomal recessive neurodegenerative disease characterized by diabetes mellitus, optic atrophy, diabetes insipidus, and deafness (DIDMOAD). Additional clinical features may include renal abnormalities, ataxia, dementia or mental retardation, and diverse psychiatric illnesses. The minimal diagnostic criteria for Wolfram syndrome are optic atrophy and diabetes mellitus of juvenile onset. Hearing impairment in Wolfram syndrome is typically progressive and mainly affects the higher frequencies, but a small fraction of affected individuals have congenital deafness (summary by Rendtorff et al., 2011).Autosomal dominant mutations in the WFS1 gene have been found to cause low-frequency nonsyndromic deafness (OMIM ) as well as a Wolfram syndrome-like phenotype (OMIM ) in which affected individuals have hearing impairment with diabetes mellitus and/or optic atrophy. Genetic Heterogeneity of Wolfram SyndromeWolfram syndrome-2 (WFS2 ) is caused by mutation in the CISD2 gene (OMIM ) on chromosome 4q24.

Medium match AUTOSOMAL RECESSIVE SPASTIC PARAPLEGIA TYPE 20

Autosomal recessive spastic paraplegia type 20 (SPG20) is a type of complex hereditary spastic paraplegia characterized by an onset in infancy of progressive spastic paraparesis associated with distal amyotrophy, psuedobulbar palsy, motor and cognitive delays, mild cerebellar signs (dysarthria, dysdiadochokinesia, mild intention tremor), short stature and subtle skeletal abnormalities (pes cavus, mild talipes equinovarus, kyphoscoliosis). SPG20 is due to mutations in the SPG20 gene (13q13.1), which encodes the protein spartin.

Medium match MACROTHROMBOCYTOPENIA-LYMPHEDEMA-DEVELOPMENTAL DELAY-FACIAL DYSMORPHISM-CAMPTODACTYLY SYNDROME

Takenouchi-Kosaki syndrome is a highly heterogeneous autosomal dominant complex congenital developmental disorder affecting multiple organ systems. The core phenotype includes delayed psychomotor development with variable intellectual disability, dysmorphic facial features, and cardiac, genitourinary, and hematologic or lymphatic defects, including thrombocytopenia and lymphedema. Additional features may include abnormalities on brain imaging, skeletal anomalies, and recurrent infections. Some patients have a milder disease course reminiscent of Noonan syndrome (see, e.g., NS1, {163950}) (summary by Martinelli et al., 2018).

Medium match ASPARTYLGLUCOSAMINURIA; AGU

Aspartylglucosaminuria is a severe autosomal recessive lysosomal storage disorder that involves the central nervous system and causes skeletal abnormalities as well as connective tissue lesions. The most characteristic feature is progressive mental retardation. The disorder is caused by deficient activity of the lysosomal enzyme glycosylasparaginase, which results in body fluid and tissue accumulation of a series of glycoasparagines, i.e., glycoconjugates with an aspartylglucosamine moiety at the reducing end. AGU belongs to the group of disorders commonly referred to as the Finnish disease heritage (summary by Mononen et al., 1993 and Arvio and Arvio, 2002).
