Nearly all children diagnosed with autism retain their diagnosis when screened again at 8 years of age, according to a population-based study of more than 1,000 children, published in June in the Journal of Developmental Behavioral Pediatrics.

Deletions in the second half of the autism-linked gene neurexin-1 are associated with seizures and large head size, according to a study published 23 May in the European Journal of Human Genetics.
Researchers have found deletions and duplications of a small piece of chromosome 2 in individuals with autism, developmental delay, epilepsy or attention deficit hyperactivity disorder.
Researchers have identified four new mutations in the autism-linked gene neurexin-1 in individuals who have autism and severe intellectual disability, they reported 3 April in Neurobiology of Disease.
Autism and attention deficit hyperactivity disorder show genetic and neurobiological overlap, which may provide clues to the origin of both disorders, says Joel Nigg.
