Postaxial polydactyly type A7 (PAPA7) is an autosomal recessive disorder characterized by postaxial polydactyly and brachydactyly of the hands and/or feet. Features reported in some patients include syndactyly of the second and third digits of the feet, learning disabilities, and increased body weight (Umair et al., 2017; Estrada-Cuzcano et al., 2020).
