LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid de novo synthesis.4[1], 5[2]

Denominator Metabolite Explanation:

Glycosphingolipid biosynthesis.6[1], 7[2]

Ratio Explanation:

The ratio reflects SGPP1's influence on ceramide precursor availability versus its subsequent glycosylation, indicating the balance between ceramide synthesis and downstream conversion.1[1], 8[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Altered SGPP1 function may elevate ceramide levels relative to glycosylceramides.8[1], 3[2] Increased ceramides are associated with insulin resistance and dyslipidemia, potentially leading to higher HbA1c and triglyceride levels, which are observed in the associated phenotypes.9[3], 10[4], 11[5], 12[6]

Phenotype Driver:

Gene-centric:SGPP1
