Postaxial polydactyly (PAP) is one of the commonest congenital malformations. Both isolated and syndromic forms of PAP have been reported. PAP is characterized by duplication of the fifth finger/toe on the ulnar/fibular side of hands/feet. A small projection of tissue or scar mark just below the proximal interphalangeal crease can also be the only clinical finding. PAP is clinically classified into type A (PAPA) with fully developed extra digit and type B (PAPB) with incompletely developed digit. PAPA is a genetically heterogeneous disorder and exhibits either autosomal dominant or recessive manner of inheritance. Given that both isolated PAPA1 and PAPB are caused by the mutations in the GLI3 gene, PAPB may be considered as a variant of PAPA1 in genetics.
