Allele and genotype frequencies for D1S80 and 3 ' APOB in Recanati, Central Italy

The VNTR 3'APOB and D1S80 loci were studied in a sample of 179 individuals living in the Recanati Area (Central Italy). For 3'APOB, we found 34 genoty pes and 11 alleles. The system was in Hardy-Weinberg equilibrium. The obser ved and expected heterozygosity were 0.788 and 0.798 respectively. The disc rimination power was 0.96, the a-priori paternity exclusion power was 0.619 and the polymorphism information content was 0.773. For D1S80, we found 45 genotypes and 18 alleles. The system deviated significantly from Hardy-Wei nberg equilibrium. The observed and expected heterozygosity were 0.696 and 0.790 respectively. The discrimination power was 0.96, the a-priori paterni ty exclusion power was 0.617 and PIC was 0.767. The Recanati sample was com pared with the general Italian frequencies for the 3'APOB locus. A differen ce of borderline significance was detected (P = 0.04). For D1S80, the sampl e was compared with a sample from Southern Italy and no significant differe nce was detected.
