LLM Analysis

Numerator Metabolite Explanation:

GPI-anchor biosynthesis8[1], 9[2]

Denominator Metabolite Explanation:

GPI-anchor biosynthesis, Fatty acid metabolism8[1], 9[2], 10[3], 11[4]

Ratio Explanation:

The ratio reflects the balance between different acyl chain compositions of GPI-anchored phospholipids, potentially influenced by MBOAT7's role in remodeling with arachidonic acid.5[1], 6[2]

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Reduced MBOAT7 function, influenced by genetic variants, alters the phosphatidylinositol profile, contributing to lipid metabolism disorders and cholelithiasis by affecting hepatic lipid homeostasis.12[1], 6[2], 13[3]

Phenotype Driver:

Gene-centric:MBOAT7
