PGM1 and Gc subtype gene frequencies in a California Hispanic population.
The gene frequencies of the subtypes of the Gc (group-specific component) protein and PGM1 (phosphoglucomutase) enzyme systems have been determined by means of isoelectric focusing for a California Hispanic population (no. = 404). The Gc subtyping, done by immunofixation on a polyacrylamide gel, gave the following results: 1s = 0.491; 1f = 0.288; 2 = 0.218; variant = 0.0025. The PGM subtyping, done on agarose gel, gave results as follows: 1+ = 0.502; 1- = 0.266; 2+ = 0.128; 2- = 0.104. Because the gene frequencies for Hispanics in both these systems are relatively evenly balanced, the systems are of great value in Hispanic paternity investigations. The average power of exclusion is calculated to be 34.4% (Gc subtyping) and 39.8% (PGM1 subtyping).
