We understand that there isn’t just one cause of ASD. Research indicates that ASD is mostly linked to genetics. However, there are also other factors that are not related to genetics, like things in the environment.
Now, scientists can find genetic differences that lead to ASD in almost one out of every five individuals with autism.
Like most common human brain disorders, autism spectrum disorder (ASD) has a strong genetic component. UCLA CART scientists have led the field of ASD genetics for more than two decades. Advances in genetics have changed the understanding of the underlying biological basis of ASD.
The term genetic means that a feature or trait is influenced by your DNA. Your DNA contains many genes, which carry instructions for your body to function.
In most cases, this influence is passed down from parents to children through DNA. The genes that you inherit from your parents can influence how you look, for example your eye color or height, and genes can also impact your chance of developing a disorder, such as autism.
In other cases, there may be a mutation, or a change in the DNA that occurs while the sperm or egg is developing. In this case, the parents do not have the mutation in cells in their body, but their child does.

In the case of de novo, neither of the parents has the change but the change has occurred in the egg [show picture]
We get half of our genes from our mother and half of our genes from our father. Each sperm and egg contain one set of 23 chromosomes. When the sperm and egg combine during fertilization, an embryo is formed with a set of 46 chromosomes, or 23 pairs – half from the mother and half from the father. It is this unique mixing of chromosomes during fertilization that gives everyone a unique set of traits and features.
When people say that autism is genetic, or involves genetic factors, they mean that it is in the DNA. In most cases, this means that ASD can run in families and is related to genes that are passed down from parents to children. This means that if one family member has autism, there may be an increase in the chances that other family members, such as brothers and sisters, also develop autism.

Yes, autism has a large genetic component, which means that genes play a big part in determining if someone has autism. The instructions in our genes are important for guiding how our brains develop. Many of the genes linked to autism impact the development of brain cells and their connections, which can in turn impact the ways that we think and act. But genes don’t tell the whole story – environmental factors also work together with our genes to influence the chances that a person will develop autism.
There are several different types of research studies that have helped scientists and doctors to understand the genetic basis of autism. Using these methods, researchers have found that autism is highly heritable, meaning that the genes that we inherit from our parents impact our likelihood of developing ASD.
