LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid biosynthesis

Denominator Metabolite Explanation:

Sphingolipid biosynthesis

Ratio Explanation:

An elevated ratio suggests increased glycosylceramide synthesis or decreased sphingomyelin synthesis. CERS4 is involved in producing the ceramide backbone for both lipids.3[1], 4[2], 5[3], 6[4]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Altered CERS4 activity likely shifts the balance of ceramide species, affecting the downstream production of glycosylceramides and sphingomyelins.1[1], 7[2] This dysregulation of sphingolipid metabolism has been linked to both polyneuropathies and gout.8[3], 9[4]

Phenotype Driver:

Gene-centric:CERS4
