The etiology of bipolar disorder (BD) remains uncertain; both genetic background and environmental factors, such as stressful life events or substance abuse, are related to the risk of development of BD. The recent PGC cross-disorder study, 73 and a further study, 80 using different analytic approaches, further substantiated the partial overlap in polygenic influences on schizophrenia and bipolar disorder, with a genetic correlation due to common SNP markers of 0.68. This opening sentence to Goodwin and Jamison’s acclaimed and comprehensive book on bipolar disorder places the often extreme and strange-appearing symptoms of mania and depression in a more comprehensible framework of shared human experiences. 1,2 However, current treatment options do not always work for people living with these conditions. 1.

Earlier studies examining the genetic cause of bipolar disorder focused on identifying common DNA changes that could only explain a small percentage of the risk for bipolar disorder… Scientists discover biological markers for bipolar disorder . In 1987, Egeland et al18 reported evidence of genetic linkage between bipolar disorder and two polymorphic DNA markers on chromosome 11 in an extended Amish pedigree. It may be that the disease is so complex because several different markers may or may not be present in people with bipolar disorder. COVID-19 is an emerging, rapidly evolving situation. Integrative computational evaluation of genetic markers for Alzheimer's disease. The invention provides haplotypes and SNPs of the HPCALl and SV2C genes which predict the risk for developing schizophrenia or bipolar disorder and predict which patients are likely to respond to a given treatment or are more likely to experience negative side effects.
