Genetics

This blog post examines a recent study exploring the genetic basis of familial multiple sclerosis through whole-exome sequencing in a multigenerational family. It highlights how rare variants in RTN4, JAK2, and DUOX2 may contribute to disease susceptibility through effects on neuroinflammation, immune signaling, oxidative stress, and remyelination failure. The post also discusses the study’s support for an oligogenic model of multiple sclerosis, while critically considering its methodological strengths, limitations, and implications for future research.
