Embryology of familial (non-syndromic) brachydactyly of the hand

摘要

Isolated familial non-syndromic brachydactyly is interesting from the embryological point of view because the phenotypes of isolated brachydactyly are frequently overlapping, yet they are caused by different gene mutations and the ring finger is frequently relatively preserved. We review the embryology of isolated familial brachydactyly with special attention to these two features.
