title: Frequencies of salivary genetic marker systems in the Japanese population and their application to forensic medicine.
abstract: Seven salivary polymorphic systems were studied using whole and parotid saliva from random Japanese individuals. The gene frequencies obtained were: Pa+ = 0.212, Pb1 = 1.000, Pb2 = 0, Pr1 = 0.763, Pr2 = 0.237, Db+ = 0.051, Pm+ = 0.409, Ph+ = 0.026 and Amy1v = 0.013, respectively. Based on these gene frequencies, the chances for exclusion of falsely alleged fathers were calculated. The chance of exclusion on the basis of five salivary polymorphic systems was 0.305. The combined chance of exclusion utilizing only blood, serum and red-cell enzyme polymorphic systems among the Japanese population was 0.919; however, by applying salivary polymorphic systems to the calculation, the total exclusion rose to 0.944.
