at a rate greater than the general population, that excess is associated with a genetic component to the characteristic.
There has been a series of studies looking at the genome to see if a specific chromosome, or aspect of a chromosome, can be identified as associated with some forms of schizophrenia. In this section, the focus is on reviewing the latest research chronologically.
There have been a number of focal points for researchers. For example, associated with genetic susceptibility to schizophrenia is chromosome six. Four research teams, working independently, identified a short segment of chromosome six as being the locus of most genetic susceptibility to schizophrenia (Bower, 1995).
One study used data from a previous chromosome 6 analysis focusing on 265 Irish families, each of which had at least two members diagnosed with schizophrenia or related psychotic disorders. Enzymes were used to remove DNA segments at 16 separate locations. The only
