IFNL4 and malaria: In order to further evaluate the observed significant difference in birth weight between IFNL4- rs368234815 dG allele (herein IFNL4- dG allele) and the IFNL4-rs368234815 TT/TT genotype, the relationship between maternal malaria during pregnancy and IFNL4 was analysed and no significant difference was found between the two groups (Chi-square test; p-value: 0.297).
