Using 100 Marshfield-derived (MFD) microsatellite markers (screening set v.2) and DNA from 13 Pima Indians, none of whom were first degree relatives, we observed 4 marker loci on 3 different chromosomes which showed marked deviation from the reported heterozygosities for the Caucasian CEPH families. These 4 markers were also tested in 60 individuals from 8 different multigenerational pedigrees. For the marker MFD77, only a single allele was observed for all individuals tested. Our results indicate that a high degree of genetic homogeneity occurs in limited regions of the genome in the Pima Indian population. We are investigating the possibility that these regions of homogeneity might be associated with disease susceptibility in this population with a high prevalence of obesity, gallstones and diabetes mellitus.
