A rare autosomal recessive acromesomelic dysplasia characterized by severe dwarfism at birth, abnormalities confined to limbs, severe shortening and deformity of long bones, fusion or absence of carpal and tarsal bones, ball shaped fingers and, occasionally, polydactyly and absent joints. As seen in acromesomelic dysplasia, Hunter-Thomson type and acromesomelic dysplasia, Maroteaux Type, facial features and intelligence are normal.

Digits that appear disproportionately short compared to the hand/foot. The word brachydactyly is used here to describe a series distinct patterns of shortened digits (brachydactyly types A-E). This is the sense used here.
