RAB3GAP2 is a regulator of skeletal muscle endothelial cell proliferation and associated with capillary-to-fiber ratio
Skeletal muscle capillary density is correlated with physical performance and whole-body metabolic properties. Thus, we performed a genome-wide association study of skeletal muscle capillary-to-fiber ratio (C:F) (n = 603 males) and found that the rs115660502 G allele was associated (p < 5 × 10 -8) with increased C:F and reduced skeletal muscle expression of RAB3 GTPase-activating non-catalytic pr
