| Ankylosing Spondylitis (AS) is a common cause of inflammatory arthritis. The
disease is associated with the gene HLA-B27; however, only 1%–5% of HLA- B27-positive individuals develop ankylosing spondylitis, and there is increasing
evidence to suggest that other genes must also be involved. Over the last few
years, the development of high-throughput microarray-based single-nucleotide
polymorphism (SNP) genotyping techniques and genome-wide association
studies (GWAS) have helped to highlight non-HLA genetic risk factors
associated with AS. In this study, we investigated the association between SNP
rs10865331 and Ankylosing Spondylitis in Iranian Azari patients. 57 AS
patients who fulfilled the selection criteria, were solicited sequentially at Tabriz
University of Medical Sciences Hospitals, Tabriz, Iran. Also, 50 cases as
control group were participated in this study. There were 45 men (79%) and 12
women (21%) in the patient group. Mean age of patients was 38 ± 10.4 years
(ranging 20-62). The mean BASFI score of AS patients was 7.74. Also, the
mean BASDAI score was 20.11.All of the patients were heterozygote for
rs10865331 SNP. Also, all of the cases in the control group were heterozygote
for rs10865331 SNP. This lack of association could be related to a small sample
size or racial issues. Because of this, This SNP cannot have a diagnostic
application in our population and therefore complementary study with larger
sample size is necessary to unravel this intergenic AS-associated SNP. |
