Triphalangeal thumbs-brachyectrodactyly syndrome is a very rare limb malformation syndrome of genetic origin which is characterized by polydactyly, syndactyly, brachydactyly, ectrodactyly, triphalangeal thumb and polyphalangism.[1][2][3] Onychodystrophy and anonychia are also seen often. 27 cases from seven families from Mexico and the United States have been described in medical literature.[4][5][6][7][8] It is inherited in an autosomal dominan manner and thought to be caused by mutations in the HOXD13 gene, in chromosome 2.[9]
