What is the risk factor of autism?
Environmental factors also appear to play a part. Genetics can affect your risk of some forms of autism. If you have a brother, sister, twin, or parent with ASD, you’re more likely to develop it as well. Some medical conditions have also been linked to ASD. These include genetic disorders such as fragile X syndrome and tuberous sclerosis.
Is autism inheritable?
Yes, it is. Heritable =/= ‘inheritable’ though (although autism has a lot to do with genes). Heritability is used to determine to what extent a trait is genetic within a population.
