A combination of genetic and environmental factors play a role in the development of schizophrenia.[2][3] People with a family history of schizophrenia who suffer a transient psychosis have a 20-40% chance of being diagnosed one year later.[23]
Estimates of heritability vary because of the difficulty in separating the effects of genetics and the environment.[24] The greatest risk for developing schizophrenia is having a first-degree relative with the disease (risk is 6.5%); more than 40% of monozygotic twins of those with schizophrenia are also affected.[3] It is likely that many genes are involved, each of small effect and unknown transmission and expression.[3] Many possible candidates have been proposed, including specific copy number variations, NOTCH4, and histone protein loci.[25] A number of genome-wide associations such as zinc finger protein 804A have also been linked.[26] There appears to be significant overlap in the genetics of schizophrenia and Bipolar disorder.[27]

Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
Is cryptorchidism genetic or hereditary?
it is an inherited condition. if this question relates to one-stride.net the questioner is breaking the rules of that game
Can a person with a genetic disorder that has been corrected by gene transfer pass the corrected condition to his or her children?
No, because their genes will be changed.
Is cyrnix a genetic disorders?
I think you are referring to syrnix. Check out Wikipedia under Syringomyelia. Describes condition in detail. Basically, doctors do not know if it is genetic. Duke University is currently doing research to see if it is related to genetics.
Is chromosome analysis considered genetic testing?
Genetic testing is a type of medical test that identifies changes in genes, chromosomes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder. More than 77,000 genetic tests are currently in use, and others are being developed. Genetic testing involves looking for changes in: Genes : Gene tests study DNA sequences to identify variations (mutations) in genes that can cause or increase the risk of a genetic disorder. Gene tests can be narrow or large in scope, analyzing an individual DNA building block (nucleotide), one or more genes, or all of a person’s DNA (which is known as their genome). Chromosomes : Chromosomal genetic tests analyze whole chromosomes or long lengths of DNA to see if there are large genetic changes, such as an extra copy of a chromosome, that cause a genetic condition. Proteins : Biochemical genetic tests study the amount or activity level of proteins or enzymes; abnormalities in either can indicate changes to the DNA that result in a genetic disorder.

Is schizophrenia autosomal recessive or dominant?
Schizophrenia is only partially genetic, and therefore is neither recessive nor dominant.
If a 30 year old has schizophrenia could the mother have it as well?
Yes. Schizophrenia is partly genetic, meaning that if you have a relative with schizophrenia you are likely to also have schizophrenia. About 1/10 of people with a relative with schizophrenia develop schizophrenia, compared to 1/100 people without a relative with schizophrenia.
What part of the brain are associated to schizophrenia?
None, because schizophrenia is a condition determined by checklists and psychiatrists. It is not a condition derived from physical brain damage.
Why is schizophrenia called DID?
It's not. DID is an acronym for Dissociative Identity Disorder. This is a very different condition from schizophrenia.
In what psychiatric condition is Halloperidol used?
Schizophrenia
Are gentic abnormalties suspected causes in alzheimers and schizophrenia?
Genetic abnormalities
How likely is schizophrenia hereditary?
Schizophrenia is partly genetic- one out of ten people who have at least one schizophrenic relative also have schizophrenia (compared to one out of one hundred people in general). About one out of two people whose identical twins have schizophrenia also have schizophrenia. However, schizophrenia is not completely genetic. If schizophrenia was completely genetic, everyone who had an identical twin with schizophrenia would also have schizophrenia. This is not the case. Like I said before, about 50% of people whose identical twins have schizophrenia also have schizophrenia. There are environmental as well as genetic factors to schizophrenia.
Is schizophrenia terminal?
Schizophrenia is a mental disorder. It is not a condition that causes any sort of physical sickness that would lead to death.
Do people with schizophrenia remember what they do if they have an psychotic episode?
Typically yes, but it varies from person to person and condition to condition (schizophrenia isn't actually just one disorder--it's a spectrum of disorders).
Are there other names for schizophrenia?
At one point, schizophrenia was called "dementia praecox". Some people may say that "multiple personality disorder", "split personality", or "dissociative identity disorder" are other names for schizophrenia. However, the condition that these names describe is not the same as schizophrenia.
How does psychosis in schizophrenia happen?
Psychosis in schizophrenia and perhaps schizophreniform disorder appears to be related to abnormalities in the structure and chemistry of the brain, and appears to have strong genetic links
What is the difference in the expression of schizophrenia in identical twins attributed to?
The difference in the expression of schizophrenia in identical twins is attributed to a combination of genetic and environmental factors. While identical twins share the same genetic makeup, environmental influences such as stress, trauma, or drug use can lead to differences in the onset and severity of schizophrenia symptoms between twins.
