Genetic Counseling and Genetic Testing for Familial Hypercholesterolemia

Area of Science:

• Genetics
• Cardiovascular Medicine
• Clinical Practice

Background:

• Familial hypercholesterolemia (FH) is a prevalent autosomal codominant Mendelian disease.
• Key complications include xanthomas and coronary artery disease (CAD) due to elevated low-density lipoprotein (LDL) levels.
• Genetic factors significantly contribute to FH pathogenesis and progression.

Purpose of the Study:

• To summarize the epidemiology of FH based on genetic studies.
• To review pathogenic variants, genotype-phenotype correlations, and prognostic factors in FH.
• To assess the utility of genetic counseling and testing in managing FH.

Main Methods:

• Literature review of genetic studies on FH.
• Analysis of epidemiological data, genetic variants, and clinical outcomes.
• Evaluation of the role of genetic counseling and testing in FH management.

Main Results:

• FH is characterized by significant elevations in serum LDL levels.
• Genetic testing aids in FH diagnosis, risk stratification, and treatment motivation.
• Genotype-phenotype correlations provide insights into disease variability.

Conclusions:

• Genetic counseling and testing are essential tools for FH diagnosis and management.
• Implementation of genetic approaches in daily clinical practice is recommended for FH.
• Early diagnosis and risk assessment through genetic methods improve patient outcomes.
