BACKGROUND: To investigate the association of hypoxia-inducible factor-1α (HIF-1α), Janus tyrosine kinase-signal transducer and activator of transcription (JAK-STAT) gene polymorphisms with idiopathic scleritis in a Chinese Han population.
METHODS: Ten single nucleotide polymorphisms (SNP) of HIF-1α, tyrosine kinase 2 (TYK2), signal transducer and activator of transcription 3 (STAT3), signal transducer and activator of transcription 4 (STAT4), and retinoid-related orphan nuclear receptors-γ (ROR-γ) were selected for this study. A total of 496 idiopathic scleritis patients and 1009 controls were genotyped by the MassARRAY platform and iPLEX Gold Genotyping Assay. The allele and genotype frequencies were analyzed by Chi-square test and Fisher's exact test. Stratified analyses were performed based on gender and anatomic locations of idiopathic scleritis.
RESULTS: The frequencies of CC genotype (p = 6.18 × 10-4, Pc = 0.04, OR = 0.67,95%CI = 0.53-0.84) and C allele (p = 7.08 × 10-4, Pc = 0.04, OR = 0.71,95%CI = 0.58-0.87) for HIF-1α/rs2057482 were found significantly lower in idiopathic scleritis patients when compared to healthy controls. Stratified analysis depending on gender showed significant decreased frequencies of CC genotype (CC: p = 4.04 × 10-4, Pc = 0.02, OR = 0.54, 95%CI = 0.39-0.76) and C allele (C: p = 1.62 × 10-4, Pc = 0.01, OR = 0.58, 95%CI = 0.44-0.77) in male patients. Stratification analysis of rs2057482 according to location of scleritis did not show any significant difference between three subgroups and healthy controls.
CONCLUSION: This study showed association between polymorphism of HIF-1α/rs2057482 and susceptibility to idiopathic scleritis in Han Chinese male patients.
