Disruptions to brain’s ‘thermostat’ may underpin autism traits

by  /  18 August 2021

Mounting evidence suggests that autism often involves upsets in homeostatic plasticity, a set of processes neurons use to stabilize their activity. These disruptions result from a range of autism-linked mutations and may help to explain the condition’s famed heterogeneity.

How mutations in top autism gene could lead to seizures

by  /  5 August 2021

Deleterious mutations in an autism-associated gene can make neurons hyperexcitable, raising the risk of epileptic seizures.

There are no autism-specific genes, just brain genes

by ,  /  23 March 2021

There is not yet a single example of a gene that, when mutated, increases the likelihood of autism but not of other neurodevelopmental conditions, including intellectual disability.
