Gene Of Schizophrenia Essay

Schizophrenia is a mental illness that affects millions of people all over the world. This illness has a gene that is related to it and could be the key to identifying the origin of schizophrenia. Neuregulin 1, often referred to NRG-1, has been linked in several different studies and reports as a gene that is susceptible to schizophrenia. There is an array of studies that have been conducted to drive us to the conclusion that NRG1 is the gene to focus on when looking for the trigger of schizophrenia. What exactly is schizophrenia? It is mental illness or disorder that affects at least 1% of the population worldwide. At the age of 20 is when most are diagnosed; though children under 12 and adults over 40 can be diagnosed, it is at times difficult. Symptoms can range and vary per person but are not limited to: delusions and hallucinations, paranoia, disorientation, or negative symptoms. It is categorized into two different disorders and at times both: neurodevelopmental or neurodegenerative disorder (Gupta and Kulhara). Gupta and Kulhara explore the origin of when schizophrenia became known and how it

True gene because most do not concur with them that NRG-1 is the sole gene behind schizophrenia. Loh et al refer to NRG-1 as being at risk for the susceptibility, but do not fully agree that it is a risk. This goes back to a study that they conducted, it is to be noted that this study was done in Malaysia which differs from Iceland in the genetic makeup of its residents (Loh et al 2013 and Stefansson et al 2002.). In the study that was conducted by them, they found that alleles were differing between populations as well as the haplotypes that were meant to be susceptible. After all the testing was done they saw no evidence that there was a correlation between NRG-1 and
