Summaries for Brachydactyly, Type A2

About this section
NIH Rare Diseases:47 Brachydactyly type A2 is a very rare condition affecting the middle bone (middle phalanx) of the index finger and the second toe. Typically, people affected by brachydactyly type A2 have very short (hypoplastic) middle bones of these digits. In some individuals, the bone above the middle phalanx (distal phalanx) is shifted as well, so that the fingers and toes may look misshapen. There have not been reports of other symptoms associated with brachydactyly type A2. Typically, brachydactyly type A2 does not require surgery, and affected individuals are able to use their hands normally. Last updated: 10/31/2016

MalaCards based summary: Brachydactyly, Type A2, also known as brachydactyly type a2, is related to brachydactyly, type a4 and brachydactyly, and has symptoms including brachydactyly syndrome, clinodactyly of the 5th finger and abnormality of the metacarpal bones. An important gene associated with Brachydactyly, Type A2 is GDF5 (Growth Differentiation Factor 5), and among its related pathways are mTOR Pathway and Elastic fibre formation. Affiliated tissues include bone, and related mouse phenotypes are craniofacial and limbs/digits/tail.

UniProtKB/Swiss-Prot:69 Brachydactyly A2: A form of brachydactyly. Brachydactyly defines a group of inherited malformations characterized by shortening of the digits due to abnormal development of the phalanges and/or the metacarpals. In brachydactyly type A2 shortening of the middle phalanges is confined to the index finger and the second toe, all other digits being more or less normal. Because of a rhomboid or triangular shape of the affected middle phalanx, the end of the second finger usually deviates radially.

OMIM:51 Brachydactyly type A2 is an autosomal dominant disorder characterized by malformations of the middle phalanx of the... (112600) more...
