Whatis
Polygenic risk

Polygenic risk refers to the combined effect of several genes on an individual's chance of developing a particular disease or acquiring a particular trait. Unlike monogenic diseases, which are caused by a mutation in a single gene, polygenic diseases and traits are the result of the interaction of multiple genes, where each gene makes a small contribution.

Whatis
Polygenic Risk Score (PRS)

PRS is a numerical value that quantifies an individual's genetic predisposition to a particular trait or disease based on the sum of risk gene variants (alleles) taking into account the effect sizes of these alleles.
PRS is calculated using data from genome-wide genetic association studies (GWAS), which identify the most common genetic variants associated with specific traits.

Appl
Application of polygenic risk number

PRS can help predict the risk of developing complex diseases such as heart disease, diabetes and certain types of cancer.
PRS can be applied in personalized medicine to tailor therapy and preventive measures based on an individual's genetic risk.
