Q&A: My partner's first cousin has schizophrenia and I am concerned it will be passed to my child if I get pregnant.
My partner's parents were first cousins and there were no genetic disorders on his side of the family. He is from Africa (Egypt) and I am from Canada.
I know on my side of the family there are no genetic disorders, but on his side, his brother in law (also his first cousin) has schizophrenia. I was wondering if I were to get pregnant, if my child had a chance of getting this too.
There are clear and definitive genetic influences that may lead to schizophrenia. About 1 in 100 individuals develops schizophrenia. While there might be a very slight increased risk for having a child who might eventually develop schizophrenia, your risk is considerably below 1%. There are no specific tests that can currently be offered to detect either the diagnosis or susceptibility to schizophrenia.
