- Abstract
In the recent years, spontaneous abortion (SA) frequency increased awareness about medical and social-economic related problems. Human leukocyte antigen-G (HLA-G) is a non-classic HLA I molecule initially described in trophoblastic tissue in foeto-maternal interface. HLA-G polymorphism association with SA has been extensively studied. One amongst the foremost studied variants was HLA-G 14-bp Insertion (Ins)/Deletion (Del) polymorphism. Nevertheless, such a study was not performed in Tunisian population yet. We aim to investigate two HLA-G polymorphisms, 14-bp Ins/Del 3'UTR, and for the first time, codon 93 (CAC/CAT) polymorphisms association with SA risk in the Tunisian population. The results revealed HLA-G 14-bp Ins/Del polymorphism and CIns haplotype association with SA. No association of the HLA-G codon 93 (CAC/CAT) polymorphism to SA was observed. Considering both polymorphism together, female's homozygosity for 14-bp Ins/Del and for codon 93 (CAC/CAT) polymorphism may increase the risk of SA susceptibility.
