Intelligence stable across life, says 40-year autism study

by  /  15 August 2013

Children who have severe autism symptoms, epilepsy or poor intelligence and language skills fare worse as they age than their peers with milder symptoms, according to two long-term studies published in July, one of which spanned 40 years.


Molecular mechanisms: Rett, Angelman genes work together

by  /  13 August 2013

The genes involved in Rett and Angelman syndromes may collaborate to regulate the expression of other proteins, according to a study published 19 July in Biochemical and Biophysical Research Communications. This may explain the overlap in symptoms between the two disorders, the researchers say.


Genetic test highlights autism-linked chromosome blips

by  /  7 August 2013

A new clinical test for duplications or deletions of chromosomal regions is customized to detect more than 380 known changes, including many that are linked to autism. The method was published 24 June in the American Journal of Medical Genetics Part A.
