GPC5 and atrial fibrillation: For example, genetically determined Fibroblast Growth Factor 5 (FGF5) level was associated with a higher risk of AF (OR = 1.056 per-SD higher FGF5); each SD higher genetically determined Glypican 5 (GPC5) was associated with a higher risk of T2D (OR = 1.02); each SD higher in genetically determined scavenger receptor class F member 2 (SCARF2) was associated with a 0.062-SD higher WMH.
