The occurrence rates of class I HLA alleles were investigated in a sample o
f the Slovak population by a PCR-SSP method. The frequencies of HLA-A allel
es 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*1
301 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.
