Abstract Gene therapy, as an experimental therapy, is applied for the treatment of diseases through modification of genes. Gene therapy corrects the mutated genes. Somatic and germline gene therapy are two main types of gene therapy. In germline editing, normal genes are inserted into the human’s eggs or sperm, zygote, or early embryo. Therefore, the gene is transmitted to the next generation, but in somatic gene therapy, a normal gene is inserted into somatic cells and corrects the defective gene without transmission to children. Personalized medicine is a novel therapeutic protocol for the prevention and treatment of diseases that considers individuals’ responding differences to medications.  So, it raises ethical issues. Ethical concerns regarding gene therapy and personalized medicine are as follows: safety, accessibility, cost-efficiency, genetic enhancement, dignity, autonomy, identity, and social discrimination.

Abstract Bipolar Disorder (BD) is a cognitive and behavioral disease with mood fluctuation  . The 6th global problem is in adults. Disease susceptibility is affected through genetic factors, the epigenetic process marked the disease phenotype. On the other hand, the importance of DNA methylation in some neurobiological and cognitive activities such as brain development processes and activity includes psychiatric diseases like BD. Numerous long intergenic noncoding RNAs were found that regulate gene expression of several diseases and are involved in the brain and cognitive development as well as psychiatric disorders such as BD.
Despite advances in neuropsychological or biological markers discoveries which predict personalized treatment efficacy,   the clinical history and exhibition are careful and predictable markers for patient categorizing and treatment management. The aim of individualized medicine is to find vulnerability or preservative factors through genetic change.
Genetic, epigenetic factors, imaging, psychopathology and biomarkers can affect new treatments. Various studies such as family, twin, and adoption studies , linkage analysis indicated the association of HPA axis genes with vulnerability to BD. Personalized medicine applications in psychiatry focus on descriptive psychopathology and phenomenology via precise analysis and attention to each patient’s impaired brain and mood processes.
The precision medicine studies concentrate on response to lithium, main treatment of BD  , frequent mood diseases , antidepressant resistant prediction ,risk and outcome assessment. Precision medicine is a hopeful way to develop new treatments based on individual genetic features. Personalized medicine in psychiatric disorder is in the infancy phases, but promising approaches were developed for complex diseases treatment with human genome sequencing.
