WebJan 17, 2024 · Polygenic risk scores are an estimate of disease risk carried by the individual based on the risk alleles and the corresponding effect sizes obtained from the GWAS summary statistics. The GWAS summary statistics will be referred as the base and the dataset to be evaluated as the target. Webit is more commonly referred to as polygenic risk score (PRS) or genetic or genomic risk score (GRS) when describing disease risk.1 Historically, the number of alleles included in overall risk assessment have been limited, due to the relatively small size of GWAS. Genome-wide risk scores are becoming relatively common, and the number
