Autosomal recessive inheritance of juvenile periodontitis: test of a hypothesis

Abstract

The heredity of juvenile periodontitis was studied in a series of 30 families. None of the 60 parents showed any sign of this disease. Of the 52 siblings, 9 in 7 families were affected. The calculated genetic ratio concurred with the hypothesis of autosomal recessive inheritance based on the results of an earlier study of 31 families.
