While many genetic studies have confirmed that when one identical twin has autism, the other is highly likely to also have autism, few have looked at the differences in severity of traits between identical autistic twins.

If one fraternal (dizygotic) twin has autism, what is the likelihood the other will? Dr. Webb: Concordance in ASD diagnosis (the probability that both will have it) is observed in monozygotic (MZ) twin pairs at rates of 60-90%, whereas rates among dizygotic (DZ) twins are estimated at 3-31%.

If one identical twin has autism spectrum disorder (ASD), the other twin has a 76 percent chance of also being diagnosed with it. The numbers are lower for fraternal twins. The percentage of fraternal twins who each share an ASD diagnosis is 34 percent for same-sex twins and 18 percent for boy-girl pairs, Dr. Frazier said.

What if one twin is diagnosed with autism? The probability that both twins will have autism is observed in twin studies to be 60 to 90 percent among identical twins. For fraternal twins it’s 3 to 31 percent. However, there’s still a lot of unknowns when it comes to twins and autism.

Identical twins with autism spectrum disorder (ASD) often experience large differences in symptom severity even though they share the same DNA, according to an analysis funded by the National Institutes of Health. The findings suggest that identifying the causes of this variability may inform the treatment of ASD-related symptoms.

Identical twins share nearly all of their genetic information, so it would be expected that both twins would fall on the autism spectrum if there were a genetic cause. Research has shown that when one identical twin is on the autism spectrum, the other twin also falls on the autism spectrum in 60-90% of the cases.

In identical twin sets where both children had some form of ASD, it was very unusual for one to have Asperger’s and the other to have autism or PDD-NOS. In other words, when one identical twin had Asperger’s, the other usually, did, too. How Does Autism 'Miss' One Twin?

Finally, most twins will not suffer from autistic disorders, and even if one twin does develop autism, there is no guarantee that the other will develop it as well (even amongst identical twins).

Higher concordance rates for ASD diagnosis as well as more specific autism behaviors in MZ twins (“identical”) have historically been interpreted as related to genetic heritable factors although a recent analyses suggests moderate to significant shared environmental factors also contribute.(Hallmayer et al. 2011; Ronald & Hoekstra, 2011).

Previous studies have found that when one identical twin has ASD, chances are extremely likely that the other twin has it, too. The authors analyzed data from three previous studies comprising a total of 366 identical twin pairs with and without ASD.

Twin studies up to this point have shown that identical twins with autism have been more than 90% concordant, while nonidentical twins have been less than 31% concordant. 2 3 4 This is one of the major reasons researchers have concluded there is a large genetic contribution to autism.

However, because identical twins don’t both fall on the autism spectrum in 100% of cases, researchers also know that something else is involved in the development of ASD for many individuals. If one identical twin is autistic and the other twin is not, it is possible that something in the child’s environment or experience may be a factor in the child’s ASD.

In identical twins where they shared all genes, a third (36%) of the twins studied developed autism. Fraternal twins who shared 50% of their genes showed a 0% probability of developing autism. In those cases, one had autism, the other did not. When the view was from a broader autism phenotype, the probability increased in both cases.

Genetics. Several different genes appear to be involved in autism spectrum disorder. For some children , autism spectrum disorder can be associated with a genetic disorder, such as Rett syndrome or fragile X syndrome. For other children , genetic changes (mutations) may increase the risk of autism spectrum disorder.
About 1 in 54 children has been identified with autism spectrum disorder (ASD) according to estimates from CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network.
Autism Prevalence In 2020, the CDC reported that approximately 1 in 54 children in the U.S. is diagnosed with an autism spectrum disorder (ASD), according to 2016 data. Boys are four times more likely to be diagnosed with autism than girls.

Main signs of autism. Common signs of autism in adults include: finding it hard to understand what others are thinking or feeling. getting very anxious about social situations. finding it hard to make friends or preferring to be on your own. seeming blunt, rude or not interested in others without meaning to. finding it hard to say how you feel.
If your child shows any symptoms of autism spectrum disorder, you'll likely be referred to a specialist who treats children with autism spectrum disorder, such as a child psychiatrist or psychologist, pediatric neurologist, or developmental pediatrician, for an evaluation.
How to test a child for autism You may ask your child’s healthcare provider to periodically check your child for signs of autism with a developmental screening test. A screening test alone will not result in a diagnosis but can indicate if your child should see a specialist.
Autism spectrum disorder (ASD) is a developmental disability that can cause significant social, communication, and behavioral challenges. The term “spectrum” refers to the wide range of symptoms, skills, and levels of impairment that people with ASD can have. ASD affects people in different ways and can range from mild to severe.
There are many types of treatments available. These include applied behavior analysis , social skills training, occupational therapy, physical therapy, sensory integration therapy, and the use of assistive technology.
