D1S80 (pMCT118): analysis of 3 ethnic subpopulations living in Brussels.

Population genetic studies were carried out on 3 ethnic subpopulations living in Brussels (119 Belgians, 120 Turks and 137 Moroccans). DNA extraction was performed using the Chelex method. After DNA amplification the DNA fragments were separated electrophoretically in horizontal polyacrylamide gels. A total of 32 alleles (between 21 and 25 alleles in each subpopulation) including 8 "interalleles" could be differentiated. The allele frequencies were compared with population data from a German study and no significant differences could be observed.
