Association of primary ovarian insufficiency with a specific human leukocyte antigen haplotype (A*24:02-C*03:03-B*35:01) in Japanese women.

Abstract:

Primary ovarian insufficiency (POI) is a heterogeneous condition defined by the triad of oligo/amenorrhea, elevated gonadotropins and estrogen deficiency in women under the age of 40 years. Although autoimmune abnormalities appear to be involved in the development of POI, there are only a few studies with respect to human leukocyte antigen (HLA). The objective of this study was to identify an HLA allele(s) and/or haplotype(s) constituting a susceptibility factor(s) for POI. We examined 83 Japanese women with apparently idiopathic isolated POI. For controls, Japanese HLA reference data registered in the HLA Laboratory were utilized. No significant association was found for a total of 94 alleles for HLA-A, B, C, DRB1, and DQB1 loci, after both stringent Bonferroni correction and less stringent Benjamini- Hochberg (B-H) correction for multiple comparisons. By contrast, of 86 haplotypes identified for MHC class I (HLA-A, B, and C) and 31 haplotypes detected for MHC class II (HLA-DRB1 and DQB1), a single haplotype (A*24:02-C*03:03-B*35:01) remained significant after Bonferroni and B-H corrections (frequency: 4.82% in women with POI and 1.06% in the control data; p = 0.00049). The results imply that a specific HLA haplotype (A*24:02-C*03:03-B*35:01) constitutes a susceptibility factor for apparently isolated POI in Japanese women.
