Matrix metalloproteases 9 rs3918242 gene polymorphism and serum vit D in MS Egyptian patients.

The high frequency of MS, especially among women in the Middle East countries as well as the high cost of caring has become a truly public concern. T-cell trafficking across the interrupted BBB, which constitutes a core immunological feature of the disease, needs activation of matrix metallo-proteinases. MMP-9 (which represents the largest and most complex of MMP family) was a subject for functional polymorphism of rs3918242 gene, but with controversial results among different MS ethnic groups.
