Caudal dysplasia, femoral hypoplasia-unusual facies syndrome and absent radius: a new association in infant of diabetic mother?

The Caudal dysplasia syndrome (CDS) and the femoral hypoplasia-unusual facies syndrome (FHUFS) have been reported to be more frequent among infants of diabetic mothers (IDMs). Infact, uncontrolled maternal diabetes is the most common cause of both the syndromes. Till now, there is no case report to suggest absent radius as a manifestation of IDMs. The authors report a rare case of newborn, who presented with features compatible with both CDS and FHUFS with an additional feature of absent radius, which is not reported in the literature so far. The possibility that all these features represent different manifestations of the same disorder is discussed here.
