Introduction:wants to know what genes are important and affect the brain of patients with schizophrenia and Bipolar disorder, and what factors which again affects the conversion of a patient's brain through conversion.
Iiterature review: The strengths of our study include the rigorous characterization of subjects using the DIGS, a well validated diagnostic instrument. Our study also benefits from a family-based design that is robust to spurious findings from population stratification. This is of particular concern for markers like rs362719, which show marked allele frequency differences between populations. However, one limitation of our family-based sample is that we had suboptimal power to detect alleles of small effect .A second limitation is that, because the tagSNP selection was based on Phase I of the HapMap project, we did not cover the common variation inRELNas comprehensively as a tagging approach based on the more recent Phase II version of HapMap would have. Third, our sex-specific analyses were exploratory and require confirmation in additional samples.
Researeh :We selected nuclear families with affected offspring from three BP family studies: the Chicago, Hopkins, National Institute of Mental Health (NIMH) Intramural Program study ; the Clinical Neurogenetics study and the NIMH Genetics Initiative Bipolar Disorder Collaborative study . All subjects signed IRB approved informed consent forms prior to enrolling. Affected offspring were diagnosed with bipolar I disorder (N = 489), schizoaffective disorder, bipolar type , and bipolar II disorder (N = 39) using DSM-IV or Research Diagnostic Criteria. They included 335 affected females (60.5%) and 219 affected males (39.5%). Among the 554 affected offspring, 341 (61.6%) had psychotic symptoms, defined as a lifetime history of delusions and/or hallucinations.
Result: Finally, as the initial report of reducedRELNexpression levels in BP cases were found in patients with the psychotic form of the illness, we performed an additional family-based association analysis in the 341 affected offspring with psychotic symptoms (delusions and/or hallucinations). Again, the strongest evidence of transmission distortion continued to be in affected females with the rs362719 marker, although the effect size (ORFemale= 1.59) and statistical significance (P= 0.01) were lower than for the full affection phenotype, and no result from this analysis survived empirical correction for multiple testing
