[1]Schizophrenia is a chronic and severe brain disorder, though most people may call it an illness. With this disorder the person is more likely to experience “Imaginary friends”,[2] Hearing voices that are not there, and being very paranoid. The people who have schizophrenia are often withdrawn and can be agitated easily. [3]The main thought to the symptoms are known to be paranoia, although the symptoms can vary depending on the person and what type of schizophrenia that he or she may have. [6][7]There are five types of schizophrenia, which include, paranoid, disorganized, catatonic, undifferentiated, and residual schizophrenia.

The more replication happens then the higher the chance is likely to have a mutation or an error in the genes. To be less complicated the older the man gets the more likely a mutation is to occur.
[8]People with schizophrenia usually have a rare mutation which has hundreds of different genes and most likely cause brain development to be disrupted. Investigation into this gene is current, so it is not yet manageable to use the genetic information to anticipate who will acquire the disease.
[9]Scientists believe that no one gene causes the mutation,but they have found that a disturbance of the gene TOP3B, an extremely rare happening in most of the world, is a common occurrence in a unique distinct genetically population from North-eastern Finland. Disruption of TOP3B is associated with an increased risk of schizophrenia as well as with disruption of learning and functional thinking.
The investigation of the protein encoded by the TOP3B gene allowed the researchers to gain first insight into the cellular processes that might be disturbed in the affected individuals. Scientists identified about four people who did not have a functioning copy of the TOP3B gene. These people were either diagnosed as having learning difficulties or as having schizophrenia, making the evidence solid that this...

There is also a genetic factor in which the disease could be carried on by offspring. If both the environmental and genetic factors are present there is a greater chance for the disease to occur. People who have it in their genes just have a higher chance of becoming
