Ectrodactyly-Polydactyly

Van Regemorter et al. (1982) reported polydactyly and ectrodactyly in a sibship of 4 children. One boy and one male twin had postaxial polydactyly, while the male monozygotic cotwin had a lobster-claw deformity of the right foot and the fourth child, a girl, had absence of the phalanges of the right hand. They pointed to one previously reported family as probably identical.
