CD8A and leprosy: To further explore whether leprosy-associated genetic variation at chr10q24.32 modifies leprosy risk through its effect on gene expression, we investigated whether the leprosy risk locus colocalises with expression quantitative trait loci (eQTL) in skin, peripheral nerves and a range of primary immune cells; monocytes [17], B cells [18], NK cells [19], neutrophils [20], CD4+ T cells and CD8+ T cells [21].
