Genetic Testing For Autism: Use Your 23andMe DNA Raw Data

Have you taken a test with 23andMe? Well, you just have found a gold mine! Inside your 23andMe DNA Raw Data, you have 700,000+ variants that can be used to learn a world about your health, including your genetic risk for autism .

Before we jump into how you can use your 23andMe data to learn this information, let's first learn a bit about autism.

What is Autism Spectrum Disorder?

Autism, or Autism Spectrum Disorders (ASD) , is a group of neurodevelopmental disorders that are characterized by language, communication, social, and behavioral problems. The severity of these problems varies in different individuals and primarily consists of three separate conditions:

• Asperger's Syndrome,?also known as Asperger's, is a developmental disorder where the individual suffers from mild language and social impairments.
• Pervasive Developmental Disorder, and
• Full-blown autism?or atypical autism patients typically exhibit severe language and communication problems, repetitive behaviors, and limited social interests.

Prevalence of Autism Spectrum Disorder

According to a report released in 2012, ASD is quite common and affects?1 in every 54 boys?and 1 in every 68 children.

ASD is 4-5 times more common in boys than in girls and affects all races and ethnicity.

Studies so far have not established the etiology of ASD. However, it is suggested that ASD could be a combination of genetic and environmental factors.

What Are The Early Signs of Autism Spectrum Disorder?

The?early signs of ASD?or its constituent conditions are often mild and vary from person to person.?

One of the first signs that appear is in infants.?

Generally, infants are very playful, enthusiastic, full of energy, and very curious about what is happening around them.?However, a child with ASD would not be that curious about surrounding occurrences.?

A few early symptoms seen in infants and children include minimal reactions, slow development of language and communication, the slow movement of eyes, lack of responsiveness, lack of interest in communication, excessive temper and tantrums, obsessive habits, repetitive actions, etc.

Whenever a child is taken to the pediatrician for routine checkups, they check for different signs to detect any form of ASD.

In case parents doubt their child, they can request to be referred to a genetic counselor or ask the specialist to perform certain preliminary and genetic tests to confirm the same.

It has been said time and again that ASD has strong genetic roots, but nothing has been conclusively ever proved.

But, since the genetic link of ASD has not been disproved, it is being used in a large number of patients to detect ASD and its associated conditions.

Genetic testing for autism

When talking about genetic testing for ASD, we must first understand that the causes of ASD are heterogeneous, which means that the roots are multifactorial. One of the many links is genetics. A large-scale study claimed that there were about 18 genetic variations that may be associated with an increased risk of developing the disorder.?

Even though the genetic testing for ASD continues, the results we have obtained so far help divide autism and ASD into different categories, leading to each condition and disorder being diagnosed and managed differently.?

Once all these findings are integrated into a more organized format, each patient will be able to receive a personalized diagnosis and treatment based on the variations seen in him/her.

There are many genetic causes of autism, including chromosomal abnormalities and gene deletions. But it is also relieving to know that scientists are confident in devising medications against?80% of these 61 genetic mutations.?

Some genetic mutations coexisted with other comorbidities and conditions like seizures and diabetes. It is also interesting to note that these genetic variations always occur along with other connected genetic mutations and not in isolation.

So, what is the purpose of genetic testing for ASD?

It must be made clear that genetic testing does not diagnose autism in an individual. These tests only help in identifying any genetic or chromosomal changes.

Also, there is no single test that can point out an increased risk of ASD. So then, why should one advise a genetic test for ASD??

• For a better prognosis of the associated conditions
• To allow for better medical management of the disorder or conditions and other comorbidities like heart conditions, neural conditions, etc.
• It gives parents information for planning future pregnancies.
• Helps establish a familial pattern of inheritance
• Useful to get a psychological closure
• Allows connecting with other families and parents with ASD children

How Is Genetic Testing For Autism Spectrum Disorder Done?

Genetic testing for Autism Spectrum Disorder is commonly done in two tiers.?

Tier I includes:

• Chromosome Microarray Analysis
• Fragile X Syndrome Testing
• Single gene testing for specific symptoms

Tier II tests?include molecular testing. A genetic test for ASD children can help parents determine what type of treatments their child can benefit from and, more importantly, throw some light on why a child developed ASD in the first place.?

The chromosome microarray analysis and Fragile X syndrome tests are done more commonly to detect ASD. There are, however, some myths around genetic testing for ASD and autism.

• Parents feel that genetic tests lead to other health problems, but it's not true. Many genetic tests don't cause any health troubles.
• In the case of ASD, a negative genetic test result does not necessarily mean the child is not suffering from any of the conditions in the spectrum.
• A genetic test done to detect ASD does not detect infections or determine paternity.

Conclusion

Autism Spectrum Disorder is a huge umbrella under which multiple conditions manifest various symptoms. We also know that these occur due to many genetic variations in various genes that result in ASD and autism. The disorder spectrum is still under research, and we can only hope that shortly genetic testing for ASD becomes more conclusive and leads to better prognosis and quality of life for the children.
