LLM Analysis

Numerator Metabolite Explanation:

Fatty acid metabolism, xenobiotic metabolism.

Denominator Metabolite Explanation:

Urea cycle, nitric oxide synthesis.5[1], 6[2]

Ratio Explanation:

This ratio may reflect mitochondrial stress, where CPS1 dysfunction impairs the urea cycle (homoarginine related) and secondarily inhibits fatty acid oxidation, increasing acylglycine conjugates.7[1], 8[2]

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Defective CPS1 impairs ureagenesis, causing hyperammonemia, which is linked to renal dysfunction and cholelithiasis.9[1], 10[2], 11[3] This systemic metabolic disruption, reflected by the altered metabolite ratio and increased BUN and creatinine, drives the kidney failure phenotype.12[4]

Phenotype Driver:

Gene-centric:CPS1
