Genetics

This blog post explores a 2023 study investigating whether our genes can predict how multiple sclerosis (MS) will affect us, focusing on newly discovered genetic variants linked to disease severity. The research, which analyzed DNA from over 1,400 MS patients, found that key genetic markers identified in previous large studies do not reliably forecast the course or severity of MS in real-world settings. While genetics is critical for understanding MS, the current science isn’t ready to use gene tests to predict outcomes or guide treatment decisions for individual patients. The post highlights the importance of both hope and scientific rigor when interpreting new genetic discoveries, reminding those living with MS that the best care is still based on clinical expertise and personal experience, not just DNA.
