This study aimed to determine discrepancies in the urinary glycosaminoglycan profiles of autism spectrum disorder (ASD) patients (n=9) when compared with those from healthy volunteers (HVs, n=3). The guardians and/or educators for each participant also returned a validated Autism Behavior Checklist (ABC). The urinary chondroitin sulfate (CS) concentration was 46.1% lower in the ASD group than in the HV group. The ABC score and the urinary CS concentration were negatively correlated (Spearmans {rho}=- 0.2635), indicating that as the severity of the clinical aspect of this disorder increased, the urinary CS concentration decreased. These results suggest that low CS concentrations in the urine may be associated with ASD, and could be measured using a fast and low-cost method for diagnostics.
