[Polymorphism of placental alkaline phosphatase on the level of DNA and protein in the Mordovian population].

Data on DNA and enzyme polymorphisms of human placental alkaline phosphatase (PLAP) in Mordvinian populations are presented. Restriction fragment length polymorphism (RFLP) was detected after the digestion of DNA samples with Rsa I and Pst I endounucleases. The frequencies of the second (2) allele for PLAP Pst I and Rsa I were 0.
