Acromesomelic dysplasia is a type of skeletal malformation affecting distal and middle segments of the extremities. It occurs in both isolated (non-syndromic) and syndromic forms. In later case, it shows association with cardiac, respiratory, neurological and genital abnormalities. Acromesomelic dysplasia segregates in autosomal recessive mode. Mutations in three genes (GDF5, NPR2, BMPR1B) have been reported to cause different forms of acromesomelic dysplasia. In the present review, we have discussed clinical spectrum, genetics and signalopathies of isolated acromesomelic dysplasias.
