The occurrence rates of class I HLA alleles were investigated in a sample of the Slovak population by a PCR-SSP method. The frequencies of HLA-A alleles ranged from 0.00 for A*4301 to 0.2798 for A*0201-22; the frequencies of HLA-B alleles ranged from 0.00 for B 4601,B* 4801-3, B*5901,B* 7301, and B* 8101 to 0.1101 for B* 4402-10, and those of HLA-C alleles from 0.00 for Cw*1301 and Cw* 1402-3 to 0.2661 for Cw 0701-10. The occurrence rates of class I HLA alleles established in our study were compared with those in the Czech population. No significant differences were found.
