LLM Analysis

Numerator Metabolite Explanation:

Long-chain fatty acid biosynthesis.4[1], 5[2]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism.

Ratio Explanation:

The ratio reflects the rate of EPA synthesis by FADS enzymes relative to its incorporation into or the turnover of glycerophospholipids.

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Variants in the FADS gene cluster influence the activity of FADS1 and FADS2, altering levels of EPA and other fatty acids.6[1], 7[2], 8[3] This dysregulation of lipid metabolism is linked to an increased risk for pure hypercholesterolemia and other inflammatory conditions like follicular cysts.6[4], 9[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
