LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid metabolism.5[1], 6[2], 7[3]

Denominator Metabolite Explanation:

Sphingolipid metabolism.5[1], 6[2], 8[3]

Ratio Explanation:

This ratio reflects the balance of sphingomyelin species, potentially influenced by CERS4 which synthesizes precursors (C20 ceramides) for the denominator but not the numerator (C16).1[1], 9[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

No associated phenotype was provided, so a link between the CERS4 gene, the sphingomyelin ratio, and a phenotype cannot be established.

Phenotype Driver:

none
