Novel gene linked to brain size in autistic people
The gene, YTHDF2, may be one of several that contribute to an autism subtype marked by an unusually big brain.

The size of the cerebral cortex seems to depend on when neural progenitor cells multiply or differentiate into glial cells and neurons.
The new resource is the first to chart human brain development from before birth to 100 years of age.
Some genomic areas that help determine cerebellar size are associated with autism, schizophrenia and bipolar disorder, according to a new study. But heritable variants across the genome that also influence cerebellar size are not.
The X chromosome holds stronger-than-expected genetic sway over the structure of several brain regions. The genes that may underlie this oversized influence have ties to autism.
Frogs are useful for autism research for a slew of reasons, including the fact that the animals’ initial development occurs outside of the mother’s body in plain view.
Inhibiting a protein that helps cells move or change shape prevents atypical neuronal migration in 3D clusters of brain cells carrying autism-linked genetic variants.
When Holly Stessman isn’t probing autism genes, she is tending to her flock of chickens or seeking out the next great sci-fi movie.
An autism-linked mutation could make the brain grow unusually large by prompting cells to express a chemical signal better known for its connection to cancer.
A genetic therapy and an existing drug both restore typical brain size in mice missing DYRK1A, a top autism candidate gene, in the cerebral cortex, a new study shows. The animals typically have smaller brains than controls.
