Oxford researchers found 57 genes linked with MS (Prof Ebers's team). As far as I have read these genes are not linked to skin colour or ethnicity. Lower D3 levels in blood appear to predispose humans to MS. D3 is a factor in MS not the answer, (see Prof Zamboni's recent paper). People who do not get sun and vit D3 have a higher incidence of MS. This appears to be more about our life styles after the industrial revolution (working inside) rather than skin colour.
Pity this lady did not go to Brooklyn NY for her diagnosis, then she would really know if she had any stenoses or not.
