Psychiatric disorders in clinical genetics II: Individualizing recurrence risks.
ABSTRACT This is the second article of a two-part professional development series on genetic counseling for personal and family histories of psychiatric disorders. It is based on an Educational Breakout Session presented by The Psychiatric Special Interest Group of the National Society of Genetic Counselors at the 2006 Annual Education Conference. While the first article in this two part series dealt with addressing family histories of psychiatric disorders in clinical practice, the following discussion deals with the generation and provision of individualized recurrence risks for psychiatric disorders, based on empiric risk data. We present four cases that illustrate important components of and process for generating individualized risk assessment for family histories of psychiatric disorders.

ABSTRACT: In the last decade, major advances have been made in our understanding of the genetic basis of epilepsy. Genetic testing for over two dozen epilepsy-related genes is now clinically available, and healthcare providers who manage patients with epilepsy are faced with incorporating genetic information into their assessment and treatment plans. Although the clinical applications of genetic test results in the setting of epilepsy may be somewhat limited, an argument for the utility of testing can be made based upon the potential impact on treatment options, the ability to provide prognostic information, and the psychological, medical, and reproductive implications for patients and their family members. Clinicians who incorporate genetic testing into their evalua-tion of patients with epilepsy must be knowledgeable about epilepsy phenotypes and epilepsy genes, have expertise in eliciting a genetic family history that encompasses not only epilepsy but a broader range of relevant medical conditions, and possess a thor-ough understanding of genetic testing methods and outcomes. Given the complexity of genetic test results, it is crucial that informed consent to discuss the risks, benefits, and limitations of genetic testing take place with patients prior to testing. In addi-tion, many patients may benefit from genetic counseling to discuss testing options or results, address family impact or reproductive issues, and obtain access to support resources.

ABSTRACT: PURPOSE:: This study is the first survey of a random national sample of US psychiatrists to assess attitudes, knowledge, and clinical experience regarding genetics. We hypothesized that clinicians with more recent genetics training would demonstrate more positive attitudes and greater genetics knowledge and experience than those with less recent training. METHODS:: A probability sample of US psychiatrists (n = 93) was invited to participate in a mail survey regarding genetic medicine. RESULTS:: Forty-five psychiatrists completed the survey (response rate = 48%). All believed that genetics strongly or moderately influenced a person's mental health. Respondents expressed positive attitudes toward incorporating genetics into psychiatric practice, but most did not have recent genetics training or experience in referring patients to genetic counselors or ordering genetic tests. Psychiatrists who had genetics training within the previous 5 years had more experience in providing genetic services. CONCLUSIONS:: This survey identified areas of strength (positive attitudes about providing genetic services, belief in the heritability of mental illness) and future targets for educational intervention (general genetics, information about testing and counseling resources). The association between recent training and a greater level of clinical genetics experience suggests that educational efforts may be successful in preparing psychiatrists to provide genetic services in the future.Genetics in medicine: official journal of the American College of Medical Genetics 06/2008; 10(6).

ABSTRACT: The expected identification of susceptibility genes for psychiatric disorders may bring new opportunities and expectations from patients and families for the clinical translation of research findings in psychiatric genetics. In this article information is provided about familial risk of schizophrenia with the theory behind individualizing risk of recurrence highlighted. Recent new findings regarding the new genetic frontier, Copy Number Variations (CNV), are summarized and the genetic architecture of familial and sporadic schizophrenia applicable to the clinical situation is reviewed. A scenario in which genetic testing could be applied in velocardiofacial syndrome (VCFS) type schizophrenia is debated. Referring to genetic discrimination in mental disorders, reference is made to the implementation of the Federal Genetic Information non-discrimination Act (GINA) of 2008 in the USA and the Mental Health Care Act of 2002 in SA.African Journal of Psychiatry 06/2011; 14(2):105-11.
