RECESSIVE ANONYCHIA TOTALIS AND DOMINANT APLASIA (OR HYPOPLASIA) OF UPPER LATERAL INCISORS IN THE SAME KINDRED

The occurrence of 2 genetic traits, autosomal recessive anonychia and autosomal dominant hypoplasia of the upper lateral incisors (ULI) in 4 (2 males and 2 females) members of 2 subships of the same kindred, is described. Three of them also had spaced teeth and agenesis of 1 or more 3rd molars. Anonychia was also present in another dead sib. Many other cases of aplasia and/or hypoplasia of ULI, and persistence of deciduous ULI, were verified in the same kindred.
