New ray of hope for treating Rett syndrome

Up till now it was thought that Rett syndrome could not be cured. It is regarded as a severe form of autism and researchers were able to reverse the symptoms in the case of adult mice through correction of errant gene. It is being regarded as a surprising development and up till now researchers used to assume that in case the brain did not wire itself correctly during certain stages of development it would not be possible to correct the deficit. As of now it will not be possible to undertake this treatment on human beings as genetically engineered mice were used before conception but it has been figured out that neurons were intact and therefore it has encouraged new approaches. This has rekindled the hope that it might be possible to treat Rett syndrome and even autism too.

Yale researchers identify autism gene

Fred Volkmar, an autism expert along with his team at the Yale School of Medicine has been able to successfully identify a gene and region of a chromosome which causes autism in case of children. The study is based on the largest ever autism genome scan and more than hundred and twenty scientists conducted the research. The research dates back to 2002 when researchers decided to share their data and expertise in identification of autism susceptibility genes. The research was conducted under the Autism Genome Project and these are the first phase preliminary findings. Gene chip technology was deployed for finding out genetic similarities in the case of autistic individuals besides scanning up of DNA for searching copy number variations. Researchers feel that there might be five or six major genes and thirty other genes which were responsible for autism and in case a child had these genes then there was a high chance for the child being born with severe form of the disease.
