Similarly, the frequencies of allele MBL2*O at exon1 (codons 52 + 54 + 57) were also higher among all patients (dengue plus DWS) compared to healthy controls (dengue plus DWS: OR = 1.97, 95% CI 1.1–3.5, P = 0.021; DWS: OR = 2.1, 95% CI 1.0–4.5, P = 0.05), indicating an increased risk of dengue (Table 2). Here, MBL2 is linked to dengue disease.
