Through genome-wide association studies, geneticists are able to find new gene alleles that are more prevalent in people with a disorder like schizophrenia than in the general public.   

Do you think gene mapping is useful for understanding complex disorders such as schizophrenia? (Think about what the discovery of linked genes may tell us about the disorder given what you know about gene regulation, epigenetics, and variable expressivity).

If yes, how does it contribute to our ability to help people with the disorder? If no, why not?

Solution

Schizophrenia is a chronic and severe mental disorder appears in late adolescence or adulthood.It is characterized by hallucinations, delusions, depression etc. Scientists have long believed that schizophrenia is a genetic disorder. Genetic study of mental illness has found 128 jene associated with schizophrenia. Scientist had already known the families with autoimmune disorder tend to have higher rates in schizophrenia. The gene mapping revealed more than 100 schizophrenia linked sites. Gene expression is a process by which the information encoded in gene. Epigenetics is a study of heritable changes in gene expression and genetic modification excluding changes in the actual DNA sequence. Variable expressivity refers to the range of signs and symptoms that occur when one genotype produces the same allele or genotype.
