Placental enzyme polymorphism among Maharashtrians: alkaline phosphatase and lactate dehydrogenase.
The distribution of placental alkaline phosphatase and lactate dehydrogenase types in 635 placentas from various endogamous groups of Maharashtra have been studied by starch gel electrophoresis. In the case of alkaline phosphatase, 6 common phenotypes and 6 rare phenotypes (F2I1, S1S2, S2S3, I1S2, F1S2, F1I2) are encountered. The highest frequency of Pls1 allele (0.7394) and lowest frequency of Pli1 allele (0.0246) have been found in the Nava-Budha. 6 cases of Cal-1 and 5 cases of Cal-2 types of LDH variants have been observed in the total samples, and Muslims possess the highest frequency of Cal-1 types (3.64%). Population groups are compared with respect to Pl alleles.
