Description : Split-hand/split-foot malformation (SHFM) is a limb malformation involving the central rays of the autopod and presenting with syndactyly, median clefts of the hands and feet, and aplasia and/or hypoplasia of the phalanges, metacarpals, and metatarsals. Some patients with SHFM1 have been found to have mental retardation, ectodermal and craniofacial findings, orofacial clefting (Elliott and Evans, 2006), and neurosensory hearing loss (Tackels-Horne et al., 2001). - Genetic Heterogeneity of Split-hand/Split-foot Malformation Additional SHFM loci include SHFM2 (313350) on chromosome Xq26; SHFM3 (246560), caused by duplication of chromosome 10q24; SHFM4, caused by mutation in the TP63 gene (603273) on chromosome 3q27; SHFM5 (606708) on chromosome 2q31; and SHFM6 (225300), caused by mutation in the WNT10B gene (601906) on chromosome 12q13. Also see SHFM1D (220600) for a form of SHFM1 with deafness that may be caused by homozygous mutation in the DLX5 gene (600028).;

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in the distal-less homeobox-5 gene (DLX5, 600028.0002);

Prefixed ID : #183600;
