the finding may point to better ways to diagnose and treat these conditions. scientists have long recognized that many psychiatric disorders tend to run in families, suggesting potential genetic roots. symptoms can overlap and so distinguishing among these 5 major psychiatric syndromes can be difficult. to take a broader look, an international research consortium conducted an analysis that incorporated data from genome-wide association studies (gwas) of the 5 major disorders. the research received primary funding from nih’s national institute of mental health (nimh), along with other nih components. all had been diagnosed with at least 1 of the 5 disorders. the analysis revealed variations significantly associated with all 5 disorders.
variation in one of these, called cacna1c, had previously been linked to bipolar disorder, schizophrenia and major depression. variation in another calcium channel gene, called cacnb2, was also linked to the 5 disorders. in addition, the researchers discovered illness-linked variation for all 5 disorders in certain regions of chromosomes 3 and 10. each of these sites spans several genes, and causal factors haven’t yet been pinpointed. this region also harbors certain variations previously linked to bipolar disorder and schizophrenia. because of this, the variations couldn’t yet be used to predict or diagnose specific conditions. they may also help lead to a better understanding of the factors that cause these major mental disorders.

scientists have long recognized that many psychiatric disorders tend to run in families, suggesting potential genetic roots. such disorders it does seem that mental illness can be hereditary. but we do not fully understand how this works. mental illness may be passed on in family members for most mental disorders are caused by a combination of multiple genetic and environmental factors. this is called multifactorial inheritance. many, .
in summary, mental (psychiatric) disorders such as bipolar disorder, schizophrenia and asd have strong genetic bases (mutations, polymorphisms mental disorders are “really not at all about genetic testing where you’re testing genes or blood samples because there are no specific genetic genetics (heredity): mental illnesses sometimes run in families, suggesting that people who have a family member with a mental illness may, .
