Genomewide association study for C-reactive protein in Indians replicates known associations of common variants.

Elevated C-reactive protein (CRP) serves as an independent biomarker for acute and chronic inflammation, and is also associated with metabolic diseases. Genomewide loci regulating CRP level in Indian population, a high-risk group for metabolic illness, is unexplored. Therefore, we aimed to discover common polymorphisms associated with plasma CRP level in 4493 Indians of Indo-European origin using genomewide association study. Genomewide strong associations of two known intronic variants in hepatocyte nuclear factor-1 α gene () were identified among Indian subjects. We also detected prior associations of several variants in/near metabolic and inflammatory process genes: , , , , and with modest associations. This study confirms that Indians from Indo-European origin display similar core universal genetic factors for CRP levels.
