Genetics

This blog post examines a 2025 study that integrates bulk and single-cell transcriptomics, cis-eQTL data, Mendelian randomization, colocalization, methylation analysis, and protein interaction mapping to identify microglial genes associated with multiple sclerosis susceptibility. It highlights how the study prioritizes ARHGAP25, HLA-DRB1, MERTK, MS4A6A, and SYK as candidate therapeutic targets, with particularly strong evidence for HLA-DRB1 and SYK. The post also discusses the biological relevance of these genes in neuroinflammation, the translational potential of microglia-focused target discovery, and the limitations that must be addressed through experimental validation.
