ABSTRACT

Studies involving the locus of Waardenburg H syndrome and two others on chromosome 9 (ABO system and adenylate kinase-1) were performed on two large kindreds from northeastern Brazil. The ABO data do not agree with previous investigations, since they are not suggestive of linkage.

Keywords: Waardenburg i syndrome; Chromosome 9.
