According to the study, the researchers» genetic analysis supports previous findings that people carrying
autism genes tend to be intelligent, as well as findings about common traits between autism and high IQs — bigger brains that grow faster, better sensory and visual - spatial capabilities, and improved decision - making, to name a few.

Sebat and colleagues discovered that spontaneous structural mutations occurred at a surprisingly high rate in individuals — 20 percent — and mutations in
autism tended to disrupt
genes.
«But
genes tied to
autism tend to affect specific functions, such as the connections between brain regions that are essential to many human - specific behaviors, like speech and language.»
The study, whose first author is the quantitative biologist Ivan Iossifov, a CSHL assistant professor and on faculty at the New York Genome Center, finds that «
autism genes» - i.e., those that, when mutated, may contribute to an ASD diagnosis -
tend to have fewer mutations than most
genes in the human
gene pool.
Another striking asymmetry: when spontaneous CNVs contributing to
autism were seen in girls, they
tended to be much larger and hit many more
genes — 15
genes per CNV on average for girls vs. only 2 for boys.
