HLA-A, HLA-B and HLA-DRB1 typing was performed by sequence specific primer-polymerase chain reaction (SSP-PCR). Maximum likelihood frequencies were estimated by the zipper version of expectation maximation algorithm. Hardy-Weinberg equilibrium were determined by an exact test analogous to Fishers test by using Markovs chain, and linkage disequilibrium between pairs of loci.ResultsTwenty-two, 43 and 14 alleles were identified for HLA-A, -B and -DRB loci, respectively. The most frequent were A*02, A*24, B*35, and DRB1*04. A deficiency in the proportion of heterozygotes in HLA-A and B loci (p<0.01 and p<0.00001, respectively). The most frequent haplotypes were as follows: HLA-A*24, B*35 (7.7%) for HLA-A,-B; HLA-B*35, DRB1*04 (6.4%) for HLA-B,-DRB1 and HLA-A*24, DRB1*04 (8.9%) for HLA-A,-DRB1. For the 3 loci HLA-A,-B,-DRB1, the most frequent haplotypes were A*24, B*35, DRB1*04 (4.6%) and A*24, B*61, DRB1*04 (2.0%).ConclusionsThese results confirm the three-ethnic ancestry of the Medellin population. The predominance of Caucasian admixture differs from many other Latin-American populations and can serve as a reference for comparative studies of these populations as well as applications within the Medellin population."xsd:string |
