Many parents ask who carries the autism gene, mother or father. The short answer is both. Autism isn’t caused by a single gene from just Mom or Dad. In fact, a child’s autism risk comes from a combination of many genes inherited from both parents.
Key Genetic Insights:
- Major genetic influence: ~80% of autism risk comes from genes, which is why autism can run in families.
- Sibling risk: Having one autistic child means siblings have a higher chance of autism.
- Paternal link: Autistic siblings share nearly twice as much DNA from their father than their mother.
- Both parents: Both mom and dad can pass on autism-related genes, and factors during pregnancy (mother’s age, health) can also influence autism.
One mom of two autistic boys once asked if she “gave” her kids autism or if it came from their dad. We reassure families that no single parent is at fault – autism stems from complex genetics on both sides (plus environmental factors). Knowing that both parents can carry autism-related genes often brings some relief.
