Results of multiple sclerosis :

Risk Type	Disease risk
Main Result	Positive
Result	The distribution of -1722 T C, -1661 A G, -318 C T and +49 A G (TACA) haplotype, from the contrary, was observed to be significantly increased among controls.
Mechanism/Pathway	Following surface expression, CTLA4 is reported to suppress T cell function by inducing indoleamine 2,4-dioxygenase metabolism in dendritic cells.
