Studies on the human leukocyte antigens in patients with polycystic ovary syndrome in a Japanese population--possible susceptibility of HLA-A11 and -DRB1*0403 to patient population with polycystic ovary syndrome.
OBJECTIVE
The objective of this study was to identify the human leukocyte antigen (HLA) alleles that confer susceptibility or resistance to polycystic ovary syndrome (PCOS) in the Japanese population.


METHODS
HLA-A, -B and -C antigens were determined in 56 patients with PCOS using conventional serological method. HLA-DRB1 genotypes were determined using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in 68 patients with PCOS. As a control population, 237 healthy individuals (males and females) were examined concerning HLA-A, -B and -C antigens, and 292 individuals were examined concerning HLA-DRB1 genotypes. The rate of possession of each antigen was compared between the two populations.


RESULTS
The rate of possession of the HLA-A11 and HLA-DRB1*0403 in the patients with PCOS was significantly higher compared with that in the control group. The rate of possession of HLA-B39 in the patients with PCOS was significantly lower compared with that in the general population group.


CONCLUSIONS
Human leukocyte antigen systems appear to be linked to PCOS.
