LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid metabolism.3[1]

Denominator Metabolite Explanation:

Sphingolipid metabolism.3[1]

Ratio Explanation:

This ratio reflects the activity of CERS4, which produces long-chain (C20) ceramides (numerator precursors), relative to enzymes producing shorter-chain ceramides (denominator precursors).1[1], 3[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Altered CERS4 function changes the balance of sphingomyelin species.1[1] This dysregulation of sphingolipid metabolism is linked to inflammation and metabolic disorders, including gout and altered uric acid levels.4[2], 5[3]

Phenotype Driver:

Gene-centric:CERS4
