Hallux valgus interphalangeus and a novel mutation in HOXA13. Part of the broadening spectrum of Hand-Foot-Genital syndrome.

When evaluating foot and hand malformations in children, the orthopaedic surgeon must always consider the possibility of a more serious underlying syndrome with other accompanying abnormalities of organogenesis. We report the case of a 13-year-old female with Hand-Foot-Genital syndrome presenting to our foot and ankle clinic with tarsal coalition and hallux valgus interphalangeus - an unusual variation on the previously reported hallux varus associated with the syndrome. She was subsequently found to have a novel mutation in the HOXA13 gene. To our knowledge, this is the first report of Hand-Foot-Genital syndrome in the orthopaedic literature.
