Anonychia-onychodystrophy with brachydactyly type B and ectrodactyly is a very rare autosomal dominant disorder which is characterized by onychodystrophy, anonychia, fifth finger brachydactyly, thumb digitalization, and missing to underdeveloped distal phalanges of the fingers. It has been described in multiple members of a 5-generation English family.[1]
