Abstract
Brachydactyly type A2 (BDA2) is characterized by short or absent middle phalanges of the 2nd finger and, to a lesser degree, the 5th finger. The index finger is short and frequently deviated medially due to the abnormal triangular shape of the middle 2nd phalanx. There is variable 5th-finger clinodactyly due to the abnormal shape of the middle phalanx, as well as short and broad laterally deviated halluces and medially deviated 2nd toes.
