WebAug 3, 2024 · A polygenic risk score (PRS) is a single value estimate of an individual’s genetic liability to a trait or disease. It is calculated by the sum of an individual’s risk alleles, weighted by risk allele effect sizes derived from genome-wide associated study (GWAS) data. In recent years, PRS has generated a lot of excitement in the field due ... WebAug 8, 2024 · Recent GWAS have changed approaches from comparisons of extremely long-lived persons with controls in the normal age range [57,58] to studies of parental lifespan [14,59,60], which allow much larger samples. And new methods are being applied to conduct GWAS of longevity processes in samples of still-living individuals .
