Split hand and food deformity and the syndrome of ectrodactyly, ectodermal dysplasia, and clefting (EEC). A report of five patients.Hum Genet. 1977 Nov 02; 39(1):15-25.HG
Five new casses of ectrodactyly are described. Two patients have the syndrome of ectrodactyly, extodermal dysplasia, and clefting (EEC). In one patient with the EEC syndrome, the disorder seems to represent a new mutation. One woman with isolated ectrodactyly has a daughter with the EEC syndrome. The variation in the clinical expression of this disorder among affected members of the same family makes it difficult to determine whether there may be several mutant alleles responsible for ectrodactyly and its related manifestations.
