Genetic mutations identified in children with autism may provide more insight into this disorder
Reuters Health – French scientists have identified genetic mutations in a small number of children with autism which could provide insight into the biological basis of the disorder.
They sequenced a gene called SHANK3 in more than 200 people with autism spectrum disorders (ASD), which includes autism, and found mutations in the gene in members of three families.
ASD covers a range of problems that affect communication, social interaction, verbal skills and behavior.
"These mutations concern only a small number of individuals, but they shed light on one gene ... that is involved in autism spectrum disorders," Thomas Bourgeron, of the Pasteur Institute in Paris, said in a report in the journal Nature Genetics.
ASD, which affect six out of 1,000 children, range from mild to severe forms. The disorders are caused by chromosomal rearrangements in 3 to 6 percent of cases.
