Urinary metabolomic profiling in 22q11.2 deletion syndrome reveals microbial and mitochondrial signatures related to autism and psychosis risk.

ABSTRACT:

Aim

22q11.2 deletion syndrome (22qDS) is the most common copy-number-variation disorder, associated with multi-organ anomalies and elevated risk for schizophrenia and other neuropsychiatric conditions. Previous metabolomic studies have used blood samples, implicating mitochondrial dysfunction and amino acid imbalance, but no urinary metabolomic analysis has been reported. We aimed to characterize the urinary metabolomic profile of 22qDS.

Methods

We conducted an exploratory study comparing urine from 10 individuals with 22qDS and 10 age- and sex-matched healthy controls. Metabolites were quantified using capillary electrophoresis time-of-flight mass spectrometry and liquid chromatography time-of-flight mass spectrometry. Data were analyzed using principal component analysis a
