Children with parent-reported ASD diagnosis were more likely to have greater health care needs and difficulties accessing health care than children with other emotional or behavioral disorders (attention-deficit/hyperactivity disorder, anxiety, behavioral or conduct problems, depression, developmental delay, Down syndrome, intellectual disability, learning disability, Tourette syndrome) and children without these conditions.
Consistent with our results, (i) SCO2 deficiency and/or CCO activity defects have been reported in patients with learning disabilities including autism and (ii) mutated proteins in ASD have been found associated with p53-signaling pathways.
The comparison of our patients with previously reported deletion cases involving the 15q13q14 region demonstrated a recurrent pattern of developmental anomalies including mild dysmorphic features, cleft palate/bifid uvula, congenital heart defects (PFO or ASD), developmental delay, and learning disabilities.
