The aim of the present study was to evaluate the association of three <i>IL1A</i> SNPs, rs17561, rs1304037, and rs2856836 with the risk of endometriosis in Iranian population.
The <i>IL1A</i> rs2856836 T/C SNP was associated with susceptibility to endometriosis and the rs2856836 C allele may increase the risk of endometriosis in Iranian women.
AS patients with PA showed an earlier age of disease onset (p=0.021), longer disease duration (p=0.020) and longer duration of AS symptoms from onset (p=0.034) than AS patients without PA. We found significant associations with the presence of PA at disease onset in 14 SNPs located in 10 genes: HLA-DQB2 (rs2857210 and rs9276615), HLA-DOB (rs2857151, rs2621332 and rs1383261), JAK2 (rs7857730), IL-23R (rs11209008 and rs10489630), CYP1B1 (rs1056836), NELL1 (rs8176786), KL (rs564481), and MEFV (rs224204), IL-2RB (rs743777) and IL-1A (rs1800587).
The insertion/deletion polymorphism (rs3783553 TTCA/-) in the 3' untranslated region of interleukin-1A (IL1A) has been studied intensively and has been shown to affect tumor risk.
Our findings suggest that IL-1a rs3783553 polymorphism may modulate the risk of SCCOP recurrence in patients, particularly for patients with HPV16-positive tumors.
Recently, two small Japanese studies reported eight SNPs (rs6542095, rs11677416, rs3783550, rs3783525, rs3783553, rs2856836, rs1304037 and rs17561) at the IL1A gene locus as suggestively associated with endometriosis risk.

Although the exact mechanism through which this SNP alters risk of ovarian cancer is not clearly understood, rs17561 has also been associated with risk of endometriosis, an epidemiologic risk factor for ovarian cancer.
The four common variants (rs17561, rs1304037, rs2856836 and rs3783553) in IL1A were significantly associated with endometriosis (P=0.0024, 0.0024, 0.0014 and 0.0061, respectively).
Taken together, we examined association between rs17561 and endometriosis in an independent validation data set (524 patients and 533 healthy controls) replicating significant association (P=4.0 × 10(-5); odds ratio (OR), 1.91; 95% confidence interval (CI), 1.41-2.61).
The four common variants (rs17561, rs1304037, rs2856836 and rs3783553) in IL1A were significantly associated with endometriosis (P=0.0024, 0.0024, 0.0014 and 0.0061, respectively).
Furthermore, the OR of the 2 allele of IL-1A+889 (rs1800587) was found to be significantly increased in Europeans with AS (OR=1.357, 95% CI=1.085-1.697, P=0.007).
Polymorphisms of IL1α rs1800587, IL1β rs16944 and IL1β rs1143634 were not significantly associated with ankylosing spondylitis but inversely in this study IL1R rs2234650 was significantly associated and carriage of T allele in IL1R rs2234650 seems to be protective, while carriage of C allele result in two fold higher risk of developing AS.
Despite the small sample size and the possibility of a false negative finding, our preliminary data support the hypothesis the IL1A rs1800587 variants are not associated with AD.
The polymorphism (rs1800587) in the 5'-flanking regulatory region at -889 of the interleukin-1alpha gene has been shown to be associated with inflammatory diseases and Alzheimer's disease (AD).
We found that the statistically significant association of IL1A-889C/T (rs1800587), IL1B -31C/T (rs1143627), IL1B -511A/G (rs16944) and IL1B + 3954C/T (rs1143634) gene polymorphisms with increased susceptibility of chronic periodontitis.
A review of the literature was performed searching for the association of rs1800587 from Interleukin-1 alpha (IL1A) gene and rs1143634 from interleukin-1 beta (IL1B) gene with EARR and CP.
