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.
