7q21.3 Deletion involving enhancer sequences within the gene DYNC1I1 presents with intellectual disability and split hand-split foot malformation with decreased penetrance

Abstract excerpt

Split hand-split food malformation (SHFM) is a congenital defect of limb development that involves the central rays of the autopod and presents with median clefts of the hands and feet. It often includes syndactyly and aplasia/hypoplasia of the phalanges. SHFM is a genetic condition with high genetic heterogeneity, with at least 6 associated chromosomal loci. A locus in chromosomal region 7q21.3, associated with...
