Polygenic Risk Score Comparative Analyses Reveals Risk Disparity of Genetic Predisposition to Chronic Kidney Disease- A Multi Ancestry Approach

Abstract

Polygenic Risk Score (PRS) models are used extensively to find the population/individual risk towards disease. These predictive scores are of great help as risk scores if predicted earlier the life of individual can be saved from the chronic/ complex diseases. In this empirical assessments study, the polygenic risk score was calculated in three different ancestries (SAS, EAS and African Americans) based on more than three hundred markers. The risk score we observed indicated that average population risk scores are varied but on cumulating the ancestries the average risk score increased [~]1.3 times than individual population average risk. The parameter which varies greatly while calculating the PRS is the ancestry; it should be prerequisite that individuals of same ancestry should be taken as a one population groups while calculating the scores.
