Ramasamy et al. [43] found MS-risk SNP rs2248359, listed among the 200 prioritized MS-risk SNPs in the IMSGC meta-analysis study, to be strongly associated with increased gene expression of CYP24A1 in the frontal cortex, while two additional studies linked MS-risk SNPs rs2248137, located in CYP24A1 gene, to decreased serum vitamin D levels [41,44]. This evidence concerns the gene CYP24A1 and myeloid sarcoma.
