SUMMARY

The heritability percentage of schizophrenia is approximately 50% for first-degree relatives, such as children, and about 10% for second-degree relatives, such as grandchildren. This means that if a grandfather has schizophrenia, the risk for his grandson to inherit the condition is significantly lower than that of direct descendants. The discussion highlights the importance of understanding genetic predisposition in schizophrenia, particularly for those with a family history of the disorder.

PREREQUISITES
  • Understanding of genetic inheritance patterns
  • Familiarity with schizophrenia and its symptoms
  • Knowledge of family medical history analysis
  • Basic concepts of epidemiology related to mental health
NEXT STEPS
  • Research the genetic markers associated with schizophrenia
  • Learn about the role of environmental factors in schizophrenia development
  • Explore genetic counseling options for families with a history of schizophrenia
  • Investigate the latest studies on the heritability of mental disorders
USEFUL FOR

This discussion is beneficial for mental health professionals, genetic counselors, and individuals with a family history of schizophrenia seeking to understand their risks and the implications of genetic inheritance.

Hi

I can't find the exact answer anywhere. What is the heritance percentage of the disease for children or grandchildren from a male person?
So let's say "granddad" has the disease, what are the chances his grandson will inherit it?

Yes, my grandfather had it, but I am not afraid of the inheritance. I am just interested.
I would also like to know the chances for me being a carrier.

Thanks in advance,
fawk3s

I, too, have an interest in this subject...my great-grandmother very likely had it.
