Genetics: Small chromosome changes are rare, inherited

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.
