Autism Spectrum Disorder (ASD) is a severe form of neurological development disorder characterized by challenges in social interaction, communication, and repetitive behaviours. Though the exact causes of autism remain elusive, genetic factors play a key role.

Four types of Autism Spectrum Disorders (ASD)

Asperger’s Syndrome

Social and communication issues and cyclic behavioural patterns categorize this type of ASD. People with this type of autism disorder usually have above-average intellectual qualities. Also, they never experience any delays in normal cognition or language skills.

Pervasive Developmental Disorder

This is the most common form of ASD, which is categorized by milder signs and symptoms than other types. People suffering from this type may usually have problems with social relationships and communication. However, they never show more intense symptoms related to different types of ASD.

 This type is also known as “classic autism,” which is characterized by more intense symptoms than other types of ASD. Remarkable delays in cognitive development, poor language skills, and repetitive behaviours are some of the most typical symptoms observed in autistic disorder.

Rett Syndrome

This is a rare form of ASD. It primarily affects girls. It is characterized by intellectual disability, loss of motor skills, and abnormal hand movements.

What Is Genetic Testing?

Genetic analysis specifically determines your child’s chromosomes and DNA to monitor if they have any mutations that are linked with autism. This test can be performed with a blood sample or saliva sample.

Purpose Of The Test

The genetic test evaluates for any changes in certain genes related to autism. These mutations can be passed down from parents to their children. In a few cases, these mutations can increase the risk of developing autism. However, it doesn’t indicate that the child will develop the disorder.

Benefits of Genetic Testing

If your child has any alterations in their genes that are associated with autism, then it’s vital to diagnose early. Prompt diagnosis helps a child get the needed support as early as possible. Autism spectrum disorder is a multifaceted condition. Early intervention is vital for supporting the child to attain their complete potential. Some of the rehabilitation therapies that help with child development include behavioural therapy, speech therapy, occupational therapy, and other forms of support.

Are There Any Risks?

There are certain risks linked with genetic testing, which include the possibility of a false positive or negative result. Hence, discussing with your physician before getting genetic testing is always important.

Genetic testing can give reliable information about autism. It may also help you understand your child’s risk of developing this disorder. However, it is important to note that genetic testing cannot wholly diagnose autism, as there are several risks linked with it. Discuss with your healthcare provider whether genetic testing is suitable for you and your family.

Pros Of Genetic Testing For Autism

There are several benefits of genetic testing for autism. One of the key merits of genetic testing is that it can help identify people who may be at risk for the disorder. This helps for prompt diagnosis and intervention.

Further, genetic testing can also give vital information about a person's specific autism diagnosis. It can help support treatment plans. In a few cases, genetic testing may also disclose that an individual does not have autism, which can offer that can provide relief from uncertainty.

Well, any decision regarding diagnostic testing should always be considered by a healthcare professional who is eminent in diagnosing and treating people with an autism spectrum disorder.
