Nature: Suppression of apoptosis impairs phalangeal joint formation in the pathogenesis of brachydactyly type A1 Suppression of apoptosis impairs phalangeal joint formation in the pathogenesis of brachydactyly type A1 What is brachydactyly? Brachydactyly (brack-ee-dack-til-ee) means “short digits” and is a general term to identify fingers and toes that are shorter than normal. Brachydactyly is a genetic condition, and it happens because of a gene mutation that affects bone growth.

Understanding the Context

Brachydactyly (from Greek βραχύς (brachus) 'short' and δάκτυλος (daktulos) 'finger') is a medical term denoting the presence of abnormally short digits (fingers or toes) at birth. Brachydactyly refers to the shortness of an individual’s fingers and/or toes due to underdevelopment of the bone. There are five types of brachydactyly: types A through E, differentiated by the gene, phalanges (fingers/toes) affected, and the pattern of inheritance. Brachydactyly is when someone is born with fingers significantly shorter than they should be.
