Does having an autistic sibling give me a higher chance of an autistic child?

Question

My younger brother is 19 and he was diagnosed with autism at the age of three he’s severely autistic and I’m just wondering does it give me a higher chance of having a child with autism like does it run in families

Answer

Autism is at least partly genetic, so I would say yes. I would talk to a doctor tho as well. They know better than us

Answer

Autism is partly genetic as someone else said. I have worked with autistic children and a lot have siblings who are also autistic.

Answer

Yes. 
My sister in laws has 8 siblings and at least 3 or 4 of them has autism. 
One sister who doesn't have autism is the first to have kids and her oldest child has autism.
