One of these eQTLs affected the expression of CD52, a target for antibody therapy used in MS treatment.27 Furthermore, even closely related cell types, such as CD4+ and CD8+ T cells, showed a limited overlap between eQTLs and GWAS SNPs (21 SNPs affecting the expression of 133 genes) based on a cohort of 313 healthy individuals.24 Better understanding of disease‐associated variants in a cell‐type‐specific context can therefore inform future drug development strategies, for instance by ensuring that a drug is targeting a protein within a specific, disease pathological cell type. The gene discussed is CD4; the disease is myeloid sarcoma.
