the molecular mechanisms of the fact that more than 50% of the individuals with the same genetic make up (e.g. identical twins in schizophrenia) do not show the same psychiatric phenotype remained undefined in psychiatry. this along with the failure to find responsible genes with major effects in psychiatric disorders and lack of consistency of genetic association studies led to the current una...

linkage studies and epidemiological findings indicate that some possible genes in schizophrenia (scz) and bipolar mood disorder (bpd) are common. numerous evidences for linkage of two diseases on chromosome 22 have been found. these findings suggest that one or more genes in the 22q11.21 region may be involved in the development of both disorders. in the present case-control study, association ...

objective: the methylenetetrahydrofolate reductase (mthfr) gene polymorphism c677t is suspected to be a risk factor for psychiatric disorders, but it remains inconclusive whether the mthfr polymorphism c677t is imputed to vulnerability to schizophrenia and bipolar disorder. method: we prompted impetus to appraise this polymorphism in an iranian population. therefore, 90 patients with bipolar di...
