Patients with premature ovarian failure (POF) have been reported to have an increased frequency of the major histocompatibility class (MHC) class II antigen HLA-DR3. Here we attempt to confirm this association. We performed MHC class II immunophenotyping of HLA-DR antigens 1-10 on 102 North American caucasians with confirmed POF and 102 control caucasian women. All patients had experienced amenorrhea before the age of 40 yr and had elevated serum gonadotropins on repeated study. We found no significant increase in HLA-DR3 frequency in patients with POF when compared to our control group (P = 0.52) or even when compared to a large reference population (n = 1927) that did not differ significantly from our control group (P = 0.47). Our patients did have an increased frequency of HLA DR4 compared to this large reference population (41% vs. 23%; P < 0.001), but we were unable to demonstrate increased HLA DR4 frequency using our control group (31%; P = 0.14). In conclusion, despite a power of 99%, we were unable to confirm a significant increase in MHC class II HLA-DR3 frequency in patients with POF.
