"HLA-Cw*16 (Cw*16) is an HLA-C allele-group. The serotype identifies the more common HLA-Cw*16 gene products.[1] This allele group is most commonly found in West Africa, but A single Haplotype of Cw16 is found in Western Europe at unusually high frequencies."

"And, the Cw16 component is in strong linkage disequilibrium with the DR7-DQ2.2 component suggesting that since the haplotypes introduction into Europe there has not been adequate time for equilibration, supporting its recent introduction into Europe. This particular haplotype supports theories of migration that are more numerous than those supported by mtDNA or Y chromosomal information, many such 'smaller' migrations are evident with HLA haplotypes, suggesting a much greater complexity to human population than haploid loci make evident."

Western Migration came first, and finally genetic evidence gives support. The equilibrium they are looking for on the European continent will not be found because Europe, subsequent to a catastrophe in the Atlantic or Western Mediterranean, became overrun by the Asiatic, much like North and East Africa.
