Previous studies revealed that many genetic variations were related to sepsis susceptibility. A long non-coding RNA SOX2 overlapping transcript (SOX2OT) may play a role in mitochondrial homeostasis and antioxidative activity, but the relationship between the lncRNA SOX2OT polymorphism and sepsis susceptibility has not been reported.Methods: In this study, 474 pediatric sepsis patients and 678 healthy controls were recruited from southern China. After genotyping, the strength of the associations was evaluated through odds ratios (ORs) and 95% confidence intervals (CIs).Results: The SOX2OT rs9839776 T allele was associated with decreased susceptibility to sepsis in southern Chinese children (TT/CT vs CC adjusted OR = 0.778, 95% CI = 0.610– 0.992; P = 0.0431). Moreover, the difference in susceptibility was greater in children of age > 60 months (adjusted OR = 0.458, 95% CI = 0.234– 0.896; P = 0.0225), survivors (adjusted OR = 0.758, 95% CI = 0.585– 0.972; P = 0.0358), males (adjusted OR = 0.655, 95% CI = 0.479– 0.894; P = 0.0077) and the sepsis subgroup (adjusted OR = 0.548, 95% CI = 0.343– 0.876; P = 0.0120).Conclusion: The rs9839776 T allele may contribute to decreased sepsis risk in Chinese children. Future studies with a larger sample size are needed to verify these results.Keywords: sepsis, SOX2OT, rs9839776, susceptibility, polymorphism
