| Study Title | Plasma metabolomic profiling of individuals with autism spectrum disorder and their family members. |
| Study Summary | Autism spectrum disorder (ASD) is a common neurodevelopmental condition affecting 2.3% of 8-year-old children and is attributable to polygenic risks in most cases. Gene discovery studies catalogued >1000 genes with de novo, rare and common genetic variants that are likely associated with ASD; however, the candidate genes are rarely translated to diagnostic and treatment biomarkers. As such no pharmacological treatment option is available for targeting core symptoms. Neural circuits involved in verbal/nonverbal communications and social interaction are likely changed, which may be caused by an excitatory-inhibitory (E-I) imbalance in individuals with ASD. To date, clinical trials targeting excitatory glutamatergic or inhibitory GABAergic receptors showed mixed results. These early clinical trials highlight the unmet need of biomarkers for target populations and outcome indicators. We investigated whether plasma biomarkers would be associated with genetic risk factors and core symptoms of ASD. Plasma samples were collected for metabolomics profiling from the Autism Genetics Resource Exchange (AGRE). Detailed phenotype information is available at NIMH Data Archive (Collection ID: 4214) and can be accessed using NDAR GUID for the individuals. |

| Chromatography Summary: | The HILIC column is operated parallel to reverse phase column for simultaneous analytical separation and column flushing through the use of a dual head HPLC pump equipped with 10- port and 6-port switching valves. During operation of HILIC separation method, the MS is operated in positive ion mode and 10 μL of sample is injected onto the HILIC column while the reverse phase column is flushing with wash solution. Flow rate is maintained at 0.35 mL/min until 1.5 min, increased to 0.4 mL/min at 4 min and held for 1 min. Solvent A is 100% LC-MS grade water, solvent B is 100% LC-MS grade acetonitrile and solvent C is 2% formic acid (v/v) in LC-MS grade water. Initial mobile phase conditions are 22.5% A, 75% B, 2.5% C hold for 1.5 min, with linear gradient to 77.5% A, 20% B, 2.5% C at 4 min, hold for 1 min, resulting in a total analytical run time of 5 min. During the flushing phase (reverse phase analytical separation), the HILIC column is equilibrated with a wash solution of 77.5% A, 20% B, 2.5% C. |

| Chromatography Summary: | The C18 column is operated parallel to the HILIC column for simultaneous analytical separation and column flushing through the use of a dual head HPLC pump equipped with 10-port and 6- port switching valves. During operation of the C18 method, the MS is operated in negative ion mode and 10 μL of sample is injected onto the C18 column while the HILIC column is flushing with wash solution. Flow rate is maintained at 0.4 mL/min until 1.5 min, increased to 0.5 mL/min at 2 min and held for 3 min. Solvent A is 100% LC-MS grade water, solvent B is 100% LC-MS grade acetonitrile and solvent C is 10mM ammonium acetate in LC-MS grade water. Initial mobile phase conditions are 60% A, 35% B, 5% C hold for 0.5 min, with linear gradient to 0% A, 95% B, 5% C at 1.5 min, hold for 3.5 min, resulting in a total analytical run time of 5 min. During the flushing phase (HILIC analytical separation), the C18 column is equilibrated with a wash solution of 0% A, 95% B, 5% C until 2.5 min, followed by an equilibration solution of 60% A, 35% B, 5% C for 2.5 min. |
