CD4 and myeloid sarcoma: To explore any functional consequences of the SNPs in the MICB-LST1 region we tested these SNPs for cis-eQTL (expression quantitative trait loci) effects in peripheral blood mononuclear cells (PBMCs) of 213 MS subjects [11] as well as CD4+ T cells and CD14+ monocytes of 211 healthy controls (Table S3).
