What is the Origin of Polygenic Risk Scoring?

PRS developed as a practical application stemming from the vast data generated by Genome-Wide Association Studies (GWAS), which identified numerous genetic loci associated with common diseases and traits. The scoring method represents a major analytical advance in utilizing genetic data to move beyond single-gene disorders toward predicting the probability of complex traits influenced by many genes.

What is the Mechanism of Polygenic Risk Scoring?

The score is calculated by summing the total number of risk-associated alleles carried by an individual, with each allele weighted according to its effect size as determined by large-scale population genetic studies. This mechanism provides a personalized, probabilistic estimate of genetic predisposition, enabling the proactive and precise implementation of lifestyle, nutritional, and preventative endocrine-supportive interventions to mitigate the inherited risk profile.

Polygenic Risk Scoring

Meaning

Polygenic Risk Scoring (PRS) is a sophisticated computational methodology that systematically aggregates the small, cumulative effects of thousands of common genetic variants across an individual’s entire genome to estimate their inherited susceptibility to complex, multifactorial conditions. In the context of hormonal health, this score can provide a personalized prediction of risk for common endocrine-related disorders such as type 2 diabetes, certain hormone-sensitive cancers, or polycystic ovary syndrome (PCOS).
