title: Congenital claw-like fingers and toes. Case report of two siblings.
abstract: A report is given of two siblings with a congenital claw-like deformity of the fingers and toes, which is extremely rare. The deformity is similar to the claw of lower animals, and perhaps its cause is atavistic. The long-suppressed characteristic might have come to expression by interactions among the genes, perhaps influenced by some unknown environmental factors.
