NCIt definition : Human HOXD13 wild-type allele is located in the vicinity of 2q31.1 and is approximately
3 kb in length. This allele, which encodes homeobox protein Hox-D13, is involved in
transcriptional regulation. Mutation of the gene is associated with syndactyly type
5, sypolydactyly type 1 and brachydactyly types D and E.;
NCIt note : A 21 base-pair deletion in the exon 1 triplet repeats of the HOXD13 gene was identified
in a patient with VACTERL association (vertebral anomalies, anal atresia, congenital
cardiac disease, tracheoesophageal fistula, renal anomalies, radial dysplasia, and
other limb defects) but the linkage between HOXD13 mutations and this disease hasn't
been fully elucidated. (Am J Med Genet A. 2008;146A(24):3181-5. doi: 10.1002/ajmg.a.32426.);
