Multiple sclerosis is a neurological disease that can affect a person’s mobility and basic body functions. While we have learned more about this disease and treatments, there is much more to know, according to David Hafler, M.D., and Benjamin A. Lerner, a medical student and research fellow at Yale School of Medicine, authors of the latest Report on Progress.
Genetic factors contribute to the development of MS; studies show high rates of disease concordance in twins and other first-degree relatives. Our knowledge of MS genetics has expanded dramatically in the past decade as a result of fundamental advances in human genetics. Genome-wide association studies (GWAS), large case-control studies designed to detect genetic variants that confer modest risk for common diseases, have now identified 194 MS-associated loci that, in aggregate, account for approximately half of the genetic risk for MS. Among these loci there is significant enrichment of genes linked to lymphocyte regulation.
