Identification of important genes associated with total cholesterol using bioinformatics analysis

Area of Science:

• Genetics
• Biochemistry
• Bioinformatics

Background:

• Total cholesterol (TC) is a critical lipid biomarker.
• Understanding the genetic underpinnings of TC is vital for metabolic health.
• Previous studies have identified some genes related to TC, but a comprehensive analysis is needed.

Purpose of the Study:

• To identify genes associated with total cholesterol (TC) levels.
• To evaluate the functional relevance of identified genes.
• To provide evidence for prioritizing genes in genetic studies of lipid metabolism.

Main Methods:

• A large-scale gene-based association study involving approximately 188,578 individuals.
• Statistical analysis using Bonferroni correction for significance.
• Bioinformatics analyses to support identified gene associations.

Main Results:

• Analysis of 22,098 genes for TC levels.
• Identification of 433 significant genes associated with TC after Bonferroni correction (p < 2.3 × 10(-6)).
• Highlighting the importance of both known and novel genes, including NR1I2, STARD3, and FN1.

Conclusions:

• The study successfully identified numerous genes linked to total cholesterol.
• Findings underscore the significance of both established and newly discovered genes in TC regulation.
• The results offer valuable insights into the genetic architecture of lipid metabolism.
