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);
