Summaries for Symphalangism, Proximal, 1b

UniProtKB/Swiss-Prot : 73 Symphalangism, proximal 1B: 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, 1b, also known as sym1b, is related to proximal symphalangism and multiple synostoses syndrome 2. An important gene associated with Symphalangism, Proximal, 1b is GDF5 (Growth Differentiation Factor 5). Affiliated tissues include bone, and related phenotypes are pes planus and abnormal finger flexion creases
