LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid metabolism.2[1], 3[2]

Denominator Metabolite Explanation:

Sphingolipid metabolism.2[1], 4[2]

Ratio Explanation:

This ratio compares sphingomyelin to glycosylceramide, both derived from ceramide.2[1] CERS4 influences the ceramide pool, particularly C18:0 ceramides used for the denominator's synthesis.5[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

CERS4 activity alters the ceramide pool, affecting the balance between sphingomyelin and glycosylceramide synthesis.6[1] Dysregulation of sphingolipid metabolism is implicated in polyneuropathies.7[2], 8[3] Altered sphingolipid profiles are also associated with gout and elevated uric acid, possibly through systemic inflammation.9[4], 10[5]

Phenotype Driver:

Gene-centric:CERS4
