New genetic hypothesis for the cause of autism

OnlyPunjab.com reports:

The role of genetics in autism is believed to be significant because twin studies have found that identical twins, who have the same DNA, are much more likely to share the diagnosis than fraternal twins. However, experts have not yet identified the specific genetic components related to autism, and many experts believe that multiple genes are involved.

Researchers, led by Yong-hui Jiang of Baylor College of Medicine in Houston, propose that most cases of autism can be explained by a complex model for genetic malfunction that may or may not include an altered DNA sequence. Where the DNA sequence is intact, the researchers believe that gene expression could be faulty. They suggest that some of these genetic factors are inherited, and others occur de novo in genes of the autistic person. In this study, they formulate a five-part hypothesis on the cause of autism:
