The ieQTL analysis indicated that rs7306304-A increased expression of CLECL1 with increased proportions of microglia (interaction β = −2.72, interaction P = 5.09 × 10−37; Fig. 5d), confirming a previous finding of a microglia cell type-specific cis-eQTL for CLECL1 at this MS risk locus29. This evidence concerns the gene CLECL1 and myeloid sarcoma.
