Readers should become familiar with the entire Scientific Statement, to better understand current thinking on clinical use of polygenic scores.Ītrial fibrillation. 2021).īelow are edited excerpts from the recap section (following the Conclusions) on the five cardiometabolic disorders. PRSs will likely be too late for disease prediction in old age, but the scores may be useful for future generations - as in cascade testing for single gene disorders (Reid et al. In maturity - as risk factors appear - partitioned polygenic scores that reflect particular biological pathways may give clues to disease mechanisms and preferred treatments (Udler et al. Preventive measures may be considered, while the person is healthy. For example, in infancy through young adulthood, PRSs may identify individuals with the highest genetic risks for developing a condition. 2007).Ĭonceivably, polygenic scores may have different uses at different stages of life, even though germline DNA does not change appreciably over the life span. Other approaches also appeared (Morrison et al. The current method for combining beta values into weighted polygenic scores was proposed by Horne et al. Genome-wide association study (GWAS) analyses identified the genes (or loci) and measured their effects (called beta values). Polygenes were first recognized only through complex statistical analyses, due to their small individual effects. The study of polygenic inheritance is >100 years old, even though polygenes were invisible for nearly a century (reviewed in Rotter and Lin 2020).
