What is the Origin of Polygenic Score?

The concept originated in the field of quantitative genetics, but its clinical utility emerged with the development of Genome-Wide Association Studies (GWAS) in the early 21st century, which allowed researchers to identify thousands of common variants associated with complex phenotypes. The term polygenic is derived from the Greek poly meaning "many" and genos meaning "birth" or "origin," reflecting the influence of multiple genes. This genetic tool has facilitated a significant shift toward predictive and personalized medicine.

What is the Mechanism of Polygenic Score?

The score is calculated as a weighted sum of an individual's risk alleles, where the weight assigned to each allele is derived from its observed association strength in large-scale GWAS cohorts. The resulting numerical value places the individual on a spectrum of genetic risk relative to the general population for a specific condition. This estimation, when integrated with environmental and lifestyle factors, enables clinicians to stratify patient risk and recommend targeted, preventative behavioral modifications or more precise therapeutic strategies.

Polygenic Score

Meaning

A Polygenic Score (PGS), also known as a Polygenic Risk Score (PRS), is a quantitative genetic measure that summarizes the estimated cumulative effect of numerous common genetic variants on an individual’s predisposition to a complex trait or chronic disease. Unlike single-gene testing, which identifies rare, high-impact mutations, the PGS aggregates the small, additive contributions of thousands of single-nucleotide polymorphisms (SNPs) across the entire genome. This score provides a probabilistic estimate of an individual’s genetic liability for conditions like type 2 diabetes, cardiovascular disease, or certain cancers.
