A research has revealed that genes are linked with autism problem in many cases. Autism is a spectrum of disease, which shares three key traits. These traits are patient’s slow speed to develop language, poor social skills, and their stereotyped behaviors over and over again. Autism causes some specific defects that affect a child's ability to learn and remember.

Autism was once a rare problem in US but every 150 children are suffered by it at present. It was disclosed in a report of the Centers for Disease Control and Prevention.

The study was conducted by Christopher Walsh, at Beth Israel Deaconess Medical Center and at Children's Hospital Boston. Scientists and physicians in the United States, Turkey, Saudi Arabia, Pakistan, and Kuwait had also contributed in research work. The results of research wok were published on July 12, 2008 in the journal Science.

The autism disorder can be caused by variations in a wide variety of genes. All individuals with autism may have different gene mutations. Due to this it is difficult to find the actual cause of genetic disorders in human beings. But researchers have a common opinion that the causes of autism are genetic in 15 to 20 per cent cases. And the remaining 80 per cent cases are still unexplained.
