Variants in trust hormone receptor up the risk for autism

by  /  1 February 2010

Genetic variations that tweak the brain’s release of oxytocin — a hormone involved in social bonding and establishing trust — may increase the risk of developing autism or traits of the disorder, according to three new studies published in the past few months.

Only subset of chromosome 16 variants linked to autism

by  /  20 November 2009

Deletions or duplications of chromosomal segment 16p11.2 — previously reported as a key autism region — are seen in people with developmental delays and speech and behavioral problems, but not necessarily autism. That’s the finding from two large studies published last week of people carrying these rare genetic variations.

by  /  17 November 2008

Women who take prenatal vitamins and eat cereal supplemented with folic acid in the early months of pregnancy are less likely to have children with autism compared with women who consume less folate, suggests preliminary data from a survey presented today at the Society for Neuroscience conference.

1977 paper on the first autism twin study

by ,  /  19 March 2008

Autism is caused by poor parenting, particularly by ‘frigid’ mothers who reject their children. Such a statement would seem bizarre today. But 30 years ago parents, especially mothers, were blamed for their childrenʼs autism. But then in 1977, one study, published in the Journal of Child Psychology and Psychiatry, single-handedly turned the field around to recognize the importance of genetics.

Changes in chromosome 16 firmly linked to autism

by  /  9 January 2008

In a paper published today in The New England Journal of Medicine, researchers have identified a segment containing 25 genes on chromosome 16 that was deleted or duplicated in roughly one percent of children with autism.
