Distribution of polymorphic traits in Mazandaranian and Guilanian in Iran

In 1972, over 2,000 blood specimens were obtained from two Iranian populations, Mazandaranians and Guilanians, who live on the southern coast of the Caspian Sea. All specimens were screened for hypocatalasemics and randomly selected samples were analyzed for several blood groups (A1A2BO, MNSs, Rh, P, Fy, K, Di, Jk, Lu, Nya), red cell enzyme systems (glucose-6-phosphate dehydrogenase, phosphoglucomutase, acid phosphatase) and serum protein groups (Hp, Tf). The genetic constitution of these Iranian populations was described, and the genetic relationship to Mongolians and Caucasians was discussed.
