Did you know?
Although polygenic risk scores gained increased attention within humans, the basic idea was first introduced for selective plant and animal breeding. Similar to the modern approaches of constructing a polygenic risk score, an individual's breeding value was the sum of single nucleotide polymorphism weight by their effect on a trait. These methods were first applied to humans in the late 2000s… WebJul 27, 2024 · Information in polygenic risk scores must be contextualized to enable clinical action. There are several possible approaches to this contextualization, each of which has trade-offs relevant for clinical actionability. The imprecision in both risk estimates and thresholds for action must be communicated transparently to providers and patients.
