Summaries for Symphalangism, Proximal, 1a

UniProtKB/Swiss-Prot : 76 Symphalangism, proximal 1A: A disease characterized by the hereditary absence of the proximal interphalangeal joints. Distal interphalangeal joints are less frequently involved and metacarpophalangeal joints are rarely affected whereas carpal bone malformation and fusion are common. In the lower extremities, tarsal bone coalition is common. Conductive hearing loss is seen and is due to fusion of the stapes to the petrous part of the temporal bone.

MalaCards based summary : Symphalangism, Proximal, 1a, also known as hereditary absence of the proximal interphalangeal joints, is related to proximal symphalangism and tarsal-carpal coalition syndrome. An important gene associated with Symphalangism, Proximal, 1a is NOG (Noggin), and among its related pathways/superpathways is Cardiac Progenitor Differentiation. Affiliated tissues include bone, and related phenotypes are proximal symphalangism of hands and conductive hearing impairment

OMIM : 58 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). (185800)
