The logistic regression analysis confirmed the significant association of rs3132468-C at MICB and rs3765524-C at PLCE1 with DSS in Thai patients with dengue (one-sided P = 0.0154, per allele OR =1.57, two-sided 95% CI: 1.11–2.22 for rs3132468-C; one-sided P = 0.0226, OR = 1.48, two-sided 95% CI: 1.07–2.04 for rs3765524-C). This evidence concerns the gene PLCE1 and dengue disease.
