Is MS hereditary and can I pass it to my children?

MS isn't directly hereditary, meaning it doesn't pass from parent to child in a clear genetic pattern. However, having a parent with MS does increase a child's risk compared to the general population.

Is MS hereditary and can I pass it to my children?

MS isn't directly hereditary, meaning it doesn't pass from parent to child in a clear genetic pattern. However, having a parent with MS does increase a child's risk compared to the general population.

Here's what the numbers look like:

- General population risk: about 1 in 333 (or 0.2%)
- If you have MS, your child's risk: 3% to 5% (about 1 in 67)
- This is roughly 10 times higher than the general population

While this sounds significant, it's important to remember that there's a 95% to 97% chance your child won't develop MS. The odds are much greater that they'll be unaffected.

MS risk depends on multiple factors beyond genetics, including environmental influences and immune system characteristics. More than 200 genes have been linked to MS, but no single gene causes it.

Doctors generally don't recommend routine MRI scans for children of people with MS unless symptoms appear. If you're concerned about your children's risk, discussing this with your neurologist can help put things in perspective and address your specific situation.
