Genetics of Familial Hypercholesterolemia: New Insights

Area of Science:

• Genetics
• Cardiovascular Medicine
• Public Health

Background:

• Familial hypercholesterolemia (FH) is a prevalent monogenic disorder.
• It causes elevated plasma cholesterol, increasing the risk of premature atherosclerosis and cardiovascular disease.
• Major genetic causes include variants in LDL-R, APOB, and PCSK9, but other genes and polygenic factors also contribute.

Purpose of the Study:

• To highlight the significant prevalence of undiagnosed Familial hypercholesterolemia (FH) in the Czech Republic.
• To emphasize the need for improved detection rates and diagnostic accuracy for FH.
• To explore the potential of international collaboration in enhancing FH identification and management.

Main Methods:

• Review of current understanding of FH genetics and epidemiology.
• Analysis of FH detection rates and challenges in the Czech Republic.
• Discussion of international programs and collaborative strategies for FH screening and diagnosis.

Main Results:

• Despite successful detection efforts, approximately 80% of FH patients in the Czech Republic remain undiagnosed.
• Genetic variants in LDL-R, APOB, PCSK9, and other genes, as well as polygenic factors, underlie the FH phenotype.
• International collaboration offers a pathway to improve FH detection and genetic diagnostics.

Conclusions:

• Familial hypercholesterolemia poses a substantial, yet often unrecognized, cardiovascular risk.
• Enhanced international collaboration and advanced genetic diagnostics are essential to address the high rate of undiagnosed FH.
• Improving FH detection is critical for preventing premature cardiovascular events.
