Symphalangism, Proximal, 1a; Sym1a

Description

Proximal symphalangism-1A (SYM1A) is an autosomal dominant disorder characterized by ankylosis of the proximal interphalangeal joints, carpal and tarsal bone fusion, and, in some cases, conductive deafness (Strasburger et al., 1965). Genetic Heterogeneity of Proximal SymphalangismAnother form of proximal symphalangism (SYM1B ) is caused by mutation in the GDF5 gene (OMIM ).
