Should GRS (Genetic Risk Scores) be used as a diagnostic tool to individually define polygenic familial hypercholesterolemia?

 

 

 

 

 

 

 

 

 

 

 

No. A recent study shows that patients with FH who do not have a mutation in LDLR, APOB, and PCSK9 will not have a higher GRS compared to their unaffected relatives. This implies that the application of GRS is not instrumental as a diagnostic tool.
