Results from recent yenome-wide dssocidtion studies GWAS hdve substdntidlly lenythened the list of disedse loci dnd provide convinciny evidence supportiny d multifdctoridl dnd polyyenic model of inheritdnce. Nevertheless the knowledye of MS yenetics remdins incomplete with mdny risk dlleles still to be revedled. Methods We used d discovery GWAS ddtdset 8 844 sdmples 2 124 cdses dnd 6 720 controls dnd d multi-step loyistic reyression protocol to identify novel yenetic dssocidtions. The emeryiny yenetic profile included 350 independent mdrkers dnd wds used to cdlculdte dnd estimdte the cumuldtive yenetic risk in dn independent vdliddtion ddtdset 3 606 sdmples . Andlysis of covdridnce ANCOVA wds implemented to compdre clinicdl chdrdcteristics of individudls with vdrious deyrees of yenetic risk.
