Medium match MULTICENTRIC OSTEOLYSIS, NODULOSIS, AND ARTHROPATHY; MONA

Zankl et al. (2007) defined what they considered to be a continuous clinical spectrum involving Torg syndrome, Winchester syndrome (OMIM ), and NAO syndrome. Torg syndrome is characterized by the presence of multiple, painless, subcutaneous nodules and mild to moderate osteoporosis and osteolysis that is usually limited to the hands and feet. Radiographically, the osteolysis is accompanied by a characteristic widening of the metacarpal and metatarsal bones. Winchester syndrome presents with severe osteolysis in the hands and feet and generalized osteoporosis and bone thinning, similar to NAO, but subcutaneous nodules are characteristically absent. Various additional features including coarse face, corneal opacities, gum hypertrophy, and EKG changes have been reported. NAO syndrome, which has only been described in patients from Saudi Arabia, is generally more severe, with multiple prominent and painful subcutaneous nodules, massive osteolysis in the hands and feet, and generalized osteoporosis. Coarse face and body hirsutism are additional features.

Medium match MANNOSIDOSIS, ALPHA B, LYSOSOMAL; MANSA

Alpha-mannosidosis is an autosomal recessive lysosomal storage disease characterized by mental retardation, coarse facial features, skeletal abnormalities, hearing impairment, neurologic motor problems, and immune deficiency. Expression of the disease varies considerably, and there is a wide spectrum of clinical findings and severity. Affected children are often normal at birth and during early development. They present in early childhood with delayed psychomotor development, delayed speech, and hearing loss. Additional features include large head with prominent forehead, rounded eyebrows, flattened nasal bridge, macroglossia, widely spaced teeth, dysostosis multiplex, and motor impairment (summary by Malm and Nilssen, 2008). Classification SystemsTwo classification systems have been used to describe the clinical presentation of alpha-mannosidosis. The earlier system delineated a more severe 'type I,' which shows infantile onset, rapid mental deterioration, hypotonia, splenomegaly, severe dysostosis multiplex, and severe recurrent infections, often resulting in death by age 8 years. Individuals with the less severe 'type II' show normal early development with later childhood development of mental retardation, hearing loss, coarse facies, neurologic deterioration, and survival well into adulthood (summary by Desnick et al., 1976 and Gotoda et al., 1998). A later classification system delineated 3 clinical types. Type 1 is the mildest form, with onset after age 10 years, without skeletal abnormalities and very slow progression. Type 2 is a moderate form, with onset before age 10 years, presence of skeletal abnormalities, and slow progression with development of ataxia by age 20 to 30 years. Type 3 is the severe form, with onset in early infancy, skeletal abnormalities, and obvious progression leading to early death from primary central nervous system involvement or myopathy. Most patients belong to clinical type 2 (summary by Malm and Nilssen, 2008). Despite the clinical heterogeneity of the disorder, there are no apparent genotype/phenotype correlations (Berg et al., 1999; Riise Stensland et al., 2012).

Medium match COWDEN SYNDROME

Cowden syndrome (CS) is a difficult to recognize, under-diagnosed genodermatosis characterized by the presence of multiple hamartomas in various tissues and an increased risk for malignancies of the breast, thyroid, endometrium, kidney and colorectum. When CS is accompanied by germline PTEN mutations, it belongs to the PTEN hamartoma tumor syndrome (PHTS; see this term) group.

MGRISCE2 is an autosomal recessive disorder characterized by intrauterine growth restriction, poor postnatal growth with short stature and microcephaly, and increased sister chromatid exchange on cell studies. The disorder results from defective DNA decatenation. The pathogenesis of the disorder is similar to that of Bloom syndrome (BLM ), but patients with mutations in the TOP3A gene do not have a malar rash (summary by Martin et al., 2018).For a discussion of genetic heterogeneity of MGRISCE, see Bloom syndrome (BLM; MGRISCE1; {210900})
