Fig. 1: Overview of hypothesized mechanism of positive selection for resistance to Lassa fever mediated by LARGE1.

a, Statistical evidence for positive selection at the LARGE1 locus, adapted from Andersen et al.17. The y axis shows the composite likelihood score which integrates evidence of positive selection based on population differentiation (fixation index), long haplotype (integrated haplotype score, delta integrated haplotype score, cross-population extended haplotype homozygosity) and derived allele frequency. On the figure, p refers to the short arm of the chromosome, while q refers to the long arm. See Andersen et al.17 for details. b, Hypothesized mechanism by which decreased activity of LARGE1 increases resistance to LASV infection and Lassa fever.
