Previous studies on autism spectrum disorder (ASD) have claimed that there are cases where mutation has occurred. The aim of this study was to identify the type of mutation among autism children.

In the newer studies, new mutations have been linked with autism and they have been identified successfully. It was found that other genetic factors are also involved in this disease. However, more research helped the researchers to understand about the different genetic and environmental factors which are involved in autism.

Research work has showed that there are various factors which are linked to this case. Family traits are very important in order to understand autism. This research work helps us to understand autism from genetic point of view. There are various other factors like environmental factors.

It has been predicted that there are 11 mutations in proteins which can cause autism in human beings.

However, researchers claimed that there is no biological marker. Human behaviour profile is used in order to study autism.

ASD is a neuro-developmental disorder as claimed by the medical science. There are different symptoms, different diagnostic for everyone. The keys to all the locks are different and that where the research works are going on to find the successful key to cure this disease.
