Genetic factors can increase the vulnerability for this disorder

Detailed explanation-1: -The family of a schizophrenic client asks the nurse if there is a genetic cause of this disorder. To answer the family, which fact would the nurse cite? Conclusive evidence indicates a specific gene transmits the disorder.
Detailed explanation-2: -Deletions or duplications of genetic material in any of several chromosomes, which can affect multiple genes, are also thought to increase schizophrenia risk. In particular, a small deletion (microdeletion) in a region of chromosome 22 called 22q11 may be involved in a small percentage of cases of schizophrenia.
Detailed explanation-3: -Genetics. Schizophrenia tends to run in families, but no single gene is thought to be responsible. It’s more likely that different combinations of genes make people more vulnerable to the condition. However, having these genes does not necessarily mean you’ll develop schizophrenia.
Detailed explanation-4: -You’re more likely to get schizophrenia if someone in your family has it. If it’s a parent, brother, or sister, your chances go up by 10%. If both your parents have it, you have a 40% chance of getting it.
Detailed explanation-5: -A family history of schizophrenia is therefore associated with a higher risk of developing schizophrenia, mood disorders, and delusional disorders.
