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. A large-scale study claimed that there were about 18 genetic variations that may be associated with an increased risk of developing the disorder.Įven 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. 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.

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