What is the Origin of Polygenic Response?

The concept of polygenic inheritance emerged in the early 20th century to explain the continuous variation observed in traits like height and skin color, which did not follow simple Mendelian inheritance patterns. The term combines the Greek roots poly (many) and genes (birth/origin). The clinical relevance of polygenic response has been amplified in the 21st century by high-throughput genotyping technologies, allowing for the simultaneous assessment of thousands of genetic variants.

What is the Mechanism of Polygenic Response?

The response is governed by the cumulative influence of numerous Single Nucleotide Polymorphisms (SNPs) scattered across the genome, many of which reside in non-coding regions that regulate gene expression. These variants subtly alter the efficiency of various cellular pathways, such as nutrient sensing, receptor signaling, or hormone clearance. The combination of these small genetic influences creates a spectrum of susceptibility, which then interacts dynamically with environmental and lifestyle factors to manifest the final clinical phenotype.

Polygenic Response

Meaning

A biological or clinical outcome that is influenced by the collective effect of multiple genes, each contributing a small, additive effect, rather than being determined by a single gene mutation. This genetic architecture underlies most complex human traits and diseases, including susceptibility to metabolic syndrome, variations in hormonal levels, and individual response to pharmacological interventions. Understanding an individual’s polygenic risk score is increasingly relevant in personalized medicine for predicting complex health trajectories and tailoring wellness strategies.
