When One Identical Twin Is Schizophrenic The Other Is More Likely To Be Schizophrenic As Compared With The General Population? Why? Because identical twins share the exact same DNA. The twin studies showed that if one identical twin has schizophrenia, then there is a 30-50% chance that the other twin will have it as well.
Why Is Research Following Individuals Who Show Prodromal Symptoms Of Schizophrenia So Important? Why is research following individuals who show prodromal symptoms of schizophrenia so important? This kind of research is important because it enables investigators to identify potential warning signs that predict the onset of schizophrenia. Once such factors are identified, interventions may be
How Does Genetics Play A Role In Schizophrenia? 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
What Is The Concordance Rate Of Schizophrenia From One Identical Twin To The Other? [2] Analyzing classic studies of the genetics of schizophrenia done as early as in 1930s, Fischer concludes that a concordance rate for psychosis of about 50% in monozygotic twins seems to be a realistic estimate, which is significantly higher than that
