DNA from mothers more prone to autism-linked glitches
An autism-linked rearrangement on chromosome 16 often occurs on the copy of the chromosome inherited from the mother.

People with an extra copy of the autism-linked chromosomal region 16p11.2 have a range of characteristics, suggesting that other genetic factors are at play.
Some people with autism have an exceptional talent for music, math, art or language. What accounts for their extraordinary brains?
In children with autism, a high intelligence quotient does not guarantee good performance on a range of cognitive tests.
Using a new genetic approach, researchers are finding shared risk factors for seemingly unrelated conditions, ranging from autism to obesity.
Clinicians may need to go beyond the ‘masks’ to find autism in women.
Children with autism who receive two years of intensive therapy as toddlers appear to maintain their social and behavioral gains two years later, suggests a new study. But some researchers are skeptical that the findings will hold true outside of a clinical trial setting.
The first in-depth look at people with alterations in the 1q21.1 chromosomal region reveals a range of features, from problems with fine motor skills to autism.
More than 10 percent of people carry deletions or duplications of DNA that diminish their intellectual capacity. The findings, based on a large study of an Estonian population, suggest that the bigger the mutation, the more severe a person’s cognitive deficits.
The social deficits and repetitive behaviors seen in boys with fragile X syndrome seem to stem from their cognitive difficulties, rather than arising independently as they do in autism.
