72,73 Thus, the potential of psychiatric genomics has fueled ongoing ethical and legal debates.74,75 The availability of such complex information needs to be paired with a structured system of communicating the benefits and the risks of testing to patients to allow its effective incorporation into the process of shared medical decision making. In other areas of medicine, studies of see more communication of genetic information to patients have identified the importance of education, risk communication, and emotional support.76-78 Genetic information dramatically increases

Inhibitors,research,lifescience,medical the complexity of risk. In cancer genetics, Huiart et al79 outlined the difference between the individual risk of inheriting or transmitting

predisposing genes and the individual risk of developing the disease. This is highly relevant for mental health, as most neuropsychiatrie disorders are polygenic, and any single gene variation may Inhibitors,research,lifescience,medical have minimal impact on individual risk. Gene variations can have additive effects on the expression of a phenotype,80 or a certain gene variation might be expressed Inhibitors,research,lifescience,medical only through interaction with the environment.81 The ability of a test to identify gene variation might be different from its ability to identify the phenotype of interest. Furthermore, for example in cytochrome system testing, identifying a certain phenotype, such as slow metabolizers, may or may not have clinical utility, Inhibitors,research,lifescience,medical depending on other factors, such

as ethnicity or the medication choice involved.66 As in other areas of medicine, communicating the meanings of uncertainty, risk, and statistics in mental health conditions is difficult.82 Patient education needs to include not only information about choices but also information to enhance statistical literacy. Several research findings have helped this field. For example, using absolute risks rather than relative risks and transforming probabilities into natural frequencies displayed as pictograms facilitate communication and understanding.83,84 Inhibitors,research,lifescience,medical Specialized genetic counselors have traditionally provided risk information in medical genetics. More recently, decision aids focused on risk communication and patient education have become prominent.77,85 A recent review of risk communication interventions found that decision aids improved knowledge, but did not necessarily decrease anxiety.77 Availability of decision aids prior to the encounter with a clinician did, however, Mephenoxalone increase time for discussion of personal risk rather than education.86 Individual counseling has been identified as an important element of genetic communication to improve risk perception and to address the psychological and social effects of genetic testing on the patient and the family.71,77,87,88 Inaccurate perceptions of risk after communication were associated with the psychological health of the individual.
