PG - 482-8 LID - 10.1016/j.humimm.2010.02.001 [doi] AB - A 14-base pair (bp) long insertion (ins)/deletion (del) polymorphism in exon 8 in the 3'-untranslated region of the human leukocyte antigen (HLA)-G gene is suggested to affect transcription of the gene. Carriage of the G14bp ins is associated with low levels of soluble HLA-G and increases the risk of recurrent miscarriage (RM). Due to existence of strong linkage disequilibrium (LD) in the HLA region, the primary susceptibility genes for RM in the HLA-G region have not yet been identified. HLA-A, -B, -DRB1, and -G14bp polymorphisms were investigated in 29 Caucasian families with two or more siblings suffering unexplained RM. Strong positive LD was detected between the G14bp ins and HLA-A*01, -A*11, -A*31, -B*08, and DRB1*03, whereas strong negative LD was found between G14bp ins and HLA-A*02, -A*03, and -A*24. The frequency of haplotypes with HLA-G14bp ins inherited from the mother was significantly increased in probands with RM (p = 0.05). The increased compatibility between probands and their mothers for maternal G14 ins positive haplotypes suggests that maternal-fetal compatibility for chromosomal segments adjacent to HLA-G locus is a risk factor for female offspring to experience RM in their later reproductive life.
