LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid metabolism

Denominator Metabolite Explanation:

Plasmalogen biosynthesis

Ratio Explanation:

The ratio reflects the balance between sphingolipid and plasmalogen synthesis. FADS1/FADS2 influence the fatty acid substrates available for both pathways, thus affecting this balance.

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Genetic variation in FADS1/FADS2 alters fatty acid desaturation, impacting both sphingomyelin and plasmalogen levels. This dysregulation is linked to cholelithiasis and type 2 diabetes, likely through effects on lipid metabolism and inflammation.4[1], 5[2], 6[3], 7[4]

Phenotype Driver:

Gene-centric:FADS1/FADS2
