Molecular genetic data at two tetranucleotide repeat loci (D12S66 and D12S67) in two Indian tribal populations

Molecular genetic polymorphism study was undertaken in two tribal population groups of India at two tetranucleotide repeat loci on chromosome 12 (D12S66 and D12S67). The two tribal groups studied were Bison Horn Maria and Muria, belonging to Bastar district of Madhya Pradesh in Central India. For this study, 75 random, unrelated individuals were analyzed for D12S66 locus, whereas 76 individuals were analyzed for D12S67 locus.     

Allele frequency distribution of D8S592 (STR) and PDGFA (VNTR) among five endogamous population groups of India

Allele frequency distribution have been analyzed at D8S592 (short tandem repeat) and PDGFA (variable number of tandem repeat) among five distinct endogamous groups of India namely Ezhavas, Nayers, Arayas, Vishwakarma and Muslims. Muslims are religio-ethnic group while other populations mentioned above belong to distinct section of Hindu religion. All these populations are from Kollam district of Kerala in Southern India and speak Malayalam, an Indo-Dravidian language. A total of 228 for D8S592 and 212 for PDGFA loci, random, healthy individuals were analyzed.     

Allelic distribution of four tetranucleotide repeat loci (D3S1358, D18S51, D19S253, and FGA) in a population from Porto (North Portugal)

Allele frequencies for four short tandem repeat loci were determined in a population sample from Porto (North Portugal), using the polymerase chain reaction (PCR), in order to investigate possible genetic differences between populations from the center and north of Portugal. After denaturing PAGE electrophoresis, nine alleles were identified for D3S1358 (n = 256), 13 alleles for D18S51 (n = 235), 10 alleles for D19S253 (n = 238), and 15 alleles for FGA (n = 181). No deviations from Hardy-Weinberg equilibrium were found. The allele frequencies observed are similar to those of the Portuguese population compared except for the D3S1358 system.
