Family characteristics and multiple sclerosis

There is some evidence that multiple sclerosis (MS) may be a genetic disorder.

  • MS tends to run in families. About 15 out of 100 people who have MS have a relative with MS, most often a brother or a sister.1
  • Certain genetic characteristics associated with the immune system appear more frequently in people who have MS. These features may indicate that there are one or more genes that may increase the chance of developing MS.
