Too few or too many copies of a genetic region linked to autism produce similar effects on intelligence and social skills but opposite effects on brain structure.
Most methods used to scan the genome are missing thousands of complex variants that alter DNA structure and may contribute to autism risk.
In a feat of genetic engineering, researchers have found a way to recreate DNA duplications and deletions in human stem cells.
Watch the complete replay of Sébastien Jacquemont discussing cognitive, behavioral and neural changes underlying the link between genes and conditions such as autism.
An autism-linked rearrangement on chromosome 16 often occurs on the copy of the chromosome inherited from the mother.
