by  /  13 April 2011

Small duplications or deletions of DNA regions — called micro-copy number variations — may not lead directly to disease, but could raise the risk of autism when combined with other mutations, according to a study published in March in the American Journal of Medical Genetics Part B: Neuropsychiatric Genetics.

Prenatal tests for autism mutations pose ethical dilemmas

by  /  31 March 2011

Genetic syndromes associated with autism are increasingly being diagnosed in utero because of techniques that can identify subtle mutations in the genome. But the technology is ahead of the ethical debate on whether and how to inform parents about mutations with unknown effects.

Genetics: Cell communication pathway linked to autism

by  /  16 March 2011

Mutations in a gene that organizes synapses — the junctions between neurons — may increase the risk of autism, according to a study published in February in Autism Research. The study bolsters evidence linking a pathway involved in cell-to-cell communication to autism.

Families hint at diverse effects of chromosome 16p deletion

by  /  14 February 2011

Two new studies of families carrying glitches on a region of chromosome 16, which has been strongly associated with autism, reveal the wide range of effects caused by the variant and narrow the list of possible culprit genes.
