Recent advances in genetic testing for familial hypercholesterolemia.

Area of Science:

• Genetics
• Cardiology
• Molecular Diagnostics

Background:

• Familial hypercholesterolemia (FH) is a prevalent genetic disorder leading to premature coronary heart disease.
• FH is significantly underdiagnosed and undertreated globally.
• Genetic testing is increasingly vital for FH identification and management.

Purpose of the Study:

• To review current molecular diagnostic methods for FH.
• To highlight the advantages of next-generation sequencing (NGS) for FH diagnosis.
• To emphasize the importance of comprehensive genetic analysis in FH.

Main Methods:

• Review of molecular diagnostic strategies for FH.
• Focus on targeted next-generation sequencing (NGS) platforms.
• Inclusion of screening for copy number variants and polymorphisms.

Main Results:

• NGS platforms offer a robust approach for molecular FH diagnosis.
• Screening for copy number variants and polymorphisms aids in defining FH cases.
• Understanding genetic determinants has improved screening strategies.

Conclusions:

• Genetic analysis is essential for FH diagnosis and future therapy reimbursement.
• Effective methods must address heterogeneity, mutation types, and polygenic components.
• Standardization, databases, and education are critical as genetic testing expands.
