Genetics

This blog post examines a recent study that used whole-exome sequencing to investigate the genetic basis of multiple sclerosis in a multigenerational family with several affected members. The article identifies three rare candidate variants in RTN4, JAK2, and DUOX2, genes associated with remyelination, immune signaling, and oxidative stress. Although these variants remain classified as variants of uncertain significance, the findings support an oligogenic model of MS susceptibility and highlight the potential value of family-based sequencing for discovering rare genetic contributors to complex neurological disease.
