LLM Analysis

Numerator Metabolite Explanation:

GPI anchor biosynthesis

Denominator Metabolite Explanation:

Plasmalogen biosynthesis

Ratio Explanation:

The ratio reflects the balance between GPI anchor and plasmalogen synthesis, influenced by FADS1/FADS2 activity on fatty acid precursors.7[1], 8[2], 3[3]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

FADS1/FADS2 genetic variants alter polyunsaturated fatty acid metabolism, impacting inflammatory pathways and lipid profiles, which are associated with inflammatory bowel disease and cholelithiasis.9[1], 10[2], 11[3], 12[4], 13[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
