title: Salivary protein polymorphism in Kenya: evidence for a new AMY1 allele.
abstract: Salivary protein polymorphism was studied in 200 schoolboys, mainly Kisii and Luo from Kenya, East Africa. The frequencies of PR, PA, DB, PB and AMY1 genes were as follows: PR*1: 0.66, PA*(+): 0.18, DB*(+): 0.55, PB*2: 0.12, AMY1*A2: 0.008, AMY1*E: 0.03. These frequencies were compared with other population data, in particular from West African and US Negroes. The most interesting finding with respect to the gene frequencies is the low PB*2 frequency and the absence of AMY1*3 in Kenya. Furthermore, a new phenotype in the AMY1 system was described which suggests the presence of an allele with an estimated frequency of 0.02.
