The association between NCAM1 levels and behavioral phenotypes in children with autism spectrum disorder

Abstract Autism spectrum disorders (ASDs) are neuropsychiatric disorders associated with synaptic function and plasticity. Neural cell adhesion molecule (NCAM1) dysfunction impairs synapse formation, synaptic activity and plasticity. To explore the relationship between NCAM1 and ASD, a case-control study was conducted. This research included 40 ASD children and 39 healthy children aged 2–6 years old. We measured the levels of plasma NCAM1 in ASD and healthy control groups by ELISA kits. The severity and behavioral problems of autistic children were also examined. The level of plasma NCAM1 in ASD children was significantly lower than that in controls ( p
