Abstract

Abstract: Purpose: Our meta‐analysis of several ethnic groups (Japanese, Korean, Indian, Brazilian) revealed a significant genome‐wide association between cold medicine‐related SJS/TEN (CM‐SJS/TEN) with severe ocular complications (SOC) and IKZF1 SNPs, suggesting that IKZF1 might be a potential marker for susceptibility to CM‐SJS/TEN with SOC. In this study, we examined the association between CM‐SJS/TEN with SOC and the IKZF1 SNPs in the Thai population. Methods: 57 CM‐SJS/TEN with SOC and 171 control samples were collected at Chulalongkorn University and Mahidol University. Genomic DNA samples were genotyped for the IKZF1 SNPs at Kyoto Prefectural University of Medicine in Japan using the TaqMan SNP genotyping assay. Results: The four SNPs previously reported to be associated with CM‐SJS/TEN with SOC in the Japanese were examined in the Thai samples. Although the number of Thai cases (n = 57) was small, a significant association between CM‐SJS/TEN with SOC and IKZF1 SNPs which included rs4917014 (T vs G, OR = 2.9, p = 0.0012, Pc = 0.0049), rs4917129 (T vs C, OR = 2.8, p = 0.0026, Pc = 0.010) and rs10276619 (G vs A, OR = 1.8, p = 0.012, Pc = 0.048) was identified. Conclusion: In addition to the Japanese, Korean and Indian populations, Thai cases with CM‐SJS/TEN and SOC were significantly associated with IKZF1 SNPs. With our previous report of the critical role of IKZF1 in mucocutaneous inflammation, these results suggest that IKZF1 is important in the pathogenesis of CM‐SJS/TEN with SOC.
