Insights

Cascade genetic screening for familial hypercholesterolemia (FH) is cost-effective. This strategy identifies individuals with FH, a genetic disorder causing high LDL-cholesterol and early heart disease, improving diagnosis and management.

Area of Science:

  • Genetics
  • Cardiovascular Medicine
  • Health Economics

Background:

  • Familial hypercholesterolemia (FH) is a genetic disorder characterized by elevated LDL-cholesterol, leading to premature coronary heart disease (CHD).
  • Increased understanding of FH mutations and statin efficacy has spurred interest in genetic screening for improved diagnosis.
  • Evaluating the cost-effectiveness of genetic screening strategies is crucial for optimizing FH diagnosis and management.

Purpose of the Study:

  • To systematically review and evaluate the cost-effectiveness of genetic screening strategies for Familial hypercholesterolemia (FH).

Main Methods:

  • A systematic review of full economic evaluations of FH genetic screening strategies was conducted.
  • Searches were performed across multiple databases including Medline, Scopus, and Web of Science.
  • Data extraction and quality assessment were performed independently by two reviewers, with findings summarized in a narrative synthesis.

Main Results:

  • Seven economic evaluations published between 2002 and 2015, primarily from Europe, were included.
  • Cascade screening, involving genetic testing of relatives of diagnosed FH index cases, was the most frequently assessed strategy.
  • Cascade screening was found to be cost-effective in the majority of evaluated settings.

Conclusions:

  • The review confirms that cascade genetic screening is a cost-effective approach for diagnosing Familial hypercholesterolemia (FH).
  • Further research is warranted to assess the cost-effectiveness of cascade screening in light of new therapeutic guidelines and next-generation sequencing technologies.

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...

Principles of Pharmacogenetics: Types of Genetic Variants

The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...
