Genetics first: A fresh take on autism’s diversity

by  /  24 November 2014

Each child with autism is different from the next. One approach rapidly gaining momentum makes sense of this diversity by grouping children together based on their genetics, then looking for patterns in their symptoms. The long-term aim: personalized treatments for each subtype of autism.

Autism-linked deletion sparks symptoms via many genes

by  /  23 October 2014

Deletion or duplication of 16p11.2, a chromosomal region linked to autism, may trigger symptoms via the interactions of genes both within and outside the region at a key point in development. Researchers presented these preliminary results Sunday at the 2014 American Society of Human Genetics Annual Meeting in San Diego.

Cluster of symptoms reveals gene’s link to autism subtype

by  /  3 July 2014

CHD8, a gene that regulates the structure of DNA, is the closest thing so far to an ‘autism gene,’ suggests a study published today in Cell. People with mutations in this gene all have the same cluster of symptoms, including autism.
