RAB23 and sarcoidosis: In addition to the HLA-related eQTL/GWAS SNPs identified, our MassArray validation studies confirmed 13 of eQTL/GWAS SNPs that were significantly associated with risk of sarcoidosis (p <0.005), including validated SNPs influencing inflammation-related genes such as IL27RA, RAB23, PSORS1C1, CTNNA1, MICA, and NOTH4.
