LLM Analysis

Numerator Metabolite Explanation:

GPI anchor biosynthesis

Denominator Metabolite Explanation:

Lysophospholipid metabolism

Ratio Explanation:

The ratio reflects FADS1 activity, where lower FADS1 function is associated with higher levels of its substrate (1-oleoyl-GPI) and altered downstream lipid products.

Ratio Evidence:

metabolites not in a pathway but enzyme catalyzes one metabolite

Gene Ratio Phenotype Relationship:

Reduced FADS1 activity alters polyunsaturated fatty acid metabolism, contributing to a pro-inflammatory state and dyslipidemia, which are linked to inflammatory skin/bowel diseases and hypercholesterolemia.4[1], 3[2], 5[3], 6[4]

Phenotype Driver:

Gene-centric:FADS1
