IFN-λ4 genetic variants influence clinical malaria episodes in a cohort of Kenyan children.

ABSTRACT:

Background

Interferon (IFN)- λ4, a type III IFN, production is controlled by a dinucleotide frameshift variant (rs368234815-dG/TT) within the first exon of the IFNL4 gene. Carriers of the IFNL4-dG allele but not the IFNL4-TT allele are able to produce the IFN-λ4 protein. Patients with hepatitis C virus that do not produce the IFN-λ4 protein have higher rates of viral clearance suggesting a potential inhibitory role of IFN-λ4 in liver-tropic infections.

Methods

In this study, it was investigated whether children infected with Plasmodium falciparum, which has a well-characterized liver stage infection, would be more susceptible to clinical malaria relative to their IFNL4-rs368234815 allele. A cohort of 122 children from a malaria holoendemic region of Kenya was analysed. Episo
