Help! is multiple sclerosis a result of single or multiple gene disorder or a chromosomal abnormality?

Not genetic mostly: There are no signs that multiple sclerosis is a sign of a chromosome disorder. Although there is likely a genetic component, this appears to be a very small role. This is not the type of disease where if you have the gene, you get the disease. It tends to be sporadic. It is an auto-immune disease where antibodies attack the white matter of the brain and/or spinal cord.

None of above: The genetic issues point toward risk or susceptibility, as MS is NOT a genetic or hereditary disorder.
