GENETIC POLYMORPHISMS OF HLA-G GENE IN RHEUMATOID ARTHRITIS
Abstract
This study was aimed to evaluate the influence of Human Leukocyte Antigens- G (HLA-G) gene polymorphisms on the risk of rheumatoid arthritis (RA). In the present study, blood samples were collected from 100 rheumatoid arthritis patients and 100 healthy controls. Serum levels of HLA-G in both patients and controls were measured using ELISA kit which was shown a higher significant differences (pA which give three genotypes (GG, AG and AA). Calculations of genotypes frequency for exon 2 showed that GG and AA genotypes was associated with the disease with p- value (0.000) for both genotypes. While AG genotype showed no association with disease p value (0.449).From the results of odd ratio found that GG and AA of exon 2 gave protection effect from disease O.R( 0.29 and 0.76 ) respectively, while AG genotype acted as risk factor for disease O.R= 4.0.
