title: D1S80 VNTR locus genotypes in population of south Poland; meta-analysis pointer to genetic disequilibrium of human populations.
abstract: A highly variable number of tandem repeats (VNTRs) in a human locus D1S80 can prove to be useful for forensic science purposes. As with other genetic polymorphisms, a database of a local population allelic frequencies is needed to ensure that no departure from genetic equilibrium exists. DNA from the locus D1S80 was amplified by polymerase chain reaction (PCR) and analyzed by horizontal PAGE followed by silver staining. Samples from 133 unrelated inhabitants of Southern Poland were examined. The amplified fragment length polymorphism (AMP-FLP) analysis of the D1S80 locus demonstrated 21 alleles and heterozygosity of 0.85%. Out of the 231 possible genotypes, 47 were observed. The results were compared to the published D1S80 population studies and a meta-analysis of the genotype frequencies was performed. The G statistics revealed a deviation from genetic equilibrium in the Spanish population. Replicated goodness of fit tests showed highly significant heterogeneity of genotype distribution between tested populations. Therefore, interpretation of the casework on the basis of D1S80 locus typing may be biased by interpopulation differences.
