MBL2 and dengue disease: The frequency of the minor allele MBL2*A at codon 54 was significantly higher in all dengue patients (dengue and DWS) compared to controls (dengue plus DWS: OR = 2.1, 95% CI 1.2–3.8, P = 0.012; dengue: OR = 1.99, 95% CI 1.0–4.1, P = 0.05; DWS: OR = 2.2, 95% CI 1.05–4.8, P = 0.037), indicating that MBL2*A at codon 54 may confer an increased risk of dengue infection.
