2. Genetic Disorders/Mutations
Studies have associated more than 400 genes with the development of ASD.3‘Autism Causes.’ Southwest Autism Research & Resource Center (SARRC), 2 Oct. 2019, www.autismcenter.org/autism-causes. In some cases, the suspected genes are passed on to children from their parents, even if the parents do not have display symptoms of autism. Most genetic changes don’t lead to autism on their own.4‘What Causes Autism?’ Autism Speaks, www.autismspeaks.org/what-causes-autism.
Specific genetic causes are found in about 10 percent to 20 percent of ASD cases. This indicates that other factors play a role in the development of autism.10‘Autism Spectrum Disorder (ASD): Causes, Symptoms, Treatment & Outlook.’ Cleveland Clinic, my.clevelandclinic.org/health/diseases/8855-autism.
