Uridine monophosphate kinase polymorphism in two Venezuelan populations

A study of the uridine monophosphate kinase (UMPK) electrophoretic patterns in Venezuelan individuals from the mestizo population of Caracas and from the Warao Indians of the Nabasanuka village in the Delta of the Orinoco River are reported. Among the mestizo population, the frequency of the UMPK1, UMPK2, and UMPK3 alleles was .979, .020, and .001, respectively. A higher frequency of the UMPK3 gene was seen in the highly inbred Warao Indians than any other population studied to date.
