Autism is a topic many families think about, especially when a child shows signs of developmental differences. People often wonder what causes autism, whether it’s something in the environment, a result of parenting, or if it’s inherited through genes. The truth is, autism is a complex condition influenced by many factors. One big question is: Is autism a genetic disorder? Experts say yes, genetics plays a major role, but it’s not the whole story. Understanding this can help families better support children with autism and reduce unnecessary guilt or confusion.
Can Autism Run Through Genetics?![mn - 2025-07-11T165258.951]( "can autism help in family")
Shubhangi Gupta, Clinical Psychologist at Insync Child Development and Autism Therapy Centre in Hyderabad, explains, “Yes, autism is a genetic disorder because it has some or the other genes, our factors are there. If we take an example of any other disorder, like depression or anxiety, it is also linked to our genetics. If either of our parents has any sort of anxiety or depression, it can come through the genes in the child.”-1752233413689.png "autism")
She adds, “It depends on the child’s environment and other factors too. Those genes may or may not be triggered, depending on what kind of environment the child grows up in. If the child gets a nurturing environment, it’s possible that those genes will not trigger. But if the environment is negative or stressful, it can definitely trigger those genes.”
Autism: Genes and Beyond![3 - 2025-07-11T165200.781]( "autism in family")
Autism is a neurodevelopmental disorder, which means it affects how the brain grows and develops. According to Shubhangi, “There are genetic factors for sure. Autism is affected by the genes of the parents in the children. There are a lot of gene mutations. Sometimes, the genetic tendency can stay hidden for several generations and then suddenly become dominant in one generation.”
This means that even if no one in the family has been diagnosed with autism before, the genetic risk can still be there, waiting to show up in a new generation. Research supports the strong genetic link. A large study published in JAMA Psychiatry found that genetics accounts for up to 80% of the risk for developing autism. The study analysed data from over two million people and concluded that while environmental factors do play a role, inherited genes are the biggest factor.
Fact vs. Fiction: Clearing Up the Confusion![2 - 2025-07-11T165159.214]( "autism")
- Fact: Autism is strongly linked to genetics, but not caused by a single gene.
- Fiction: Bad parenting or vaccines cause autism as there is no scientific evidence for either.
- Fact: A supportive, nurturing environment can help children with autism thrive, even if the genetic risk is there.
- Fiction: If no one in your family has autism, your child can’t have it. Genes can skip generations or combine in new ways.
Takeaway
Autism is a neurodevelopmental disorder with a strong genetic foundation. But genes aren’t destiny. The environment and early support matter, too. If you’re concerned about autism in your family, remember: it isn’t anyone’s fault. Understanding the genetic link can help families focus on early intervention and support, giving every child the best chance to reach their potential.
