title: [The HLA system antigens in delayed sexual development].
abstract: Frequency distribution of HLA antigens of A and B loci was examined in 138 adolescent boys aged 14-18 with delayed sexual development (DSD) of stages I-III, residing in the north-eastern region of Ukraine. Increase of A28- and B40-antigens and haplotypes A1-B40, A28-B40, A10-B40 determination frequencies was established. There were revealed positive and negative correlation between some of HLA antigens and DSD. Relative and attributive risks of DSD formation were calculated.
