Ectrodactyly and proximal/intermediate interstitial deletion 7q

Abstract
We report on an individual with sever mental retardation, seizures, microcephaly unusual face, scoliosis, and cleft feet and cleft right hand. The chromosomal study showed a proximal interstitial deletion 7c (qll.23q22). From our review of the litera ture, 11 patients have been reported with ectrodactyly (split hand/split foot malforma tion) and proximal/intermediate interstitial deletions or rearrangements of 7q. The critical segment for ectrodactyly seems to be located between 7q21.2 and 7q22.1. This malformation is present in 41% of the patients whose deletion involves the critical segment.
