Many new genetic tests are used in clinical practice, and the number of available tests is growing. Two important health policy questions arise as these genetic tests become available. The first question, whether a new test should be made available, has been the focus of much recent discussion. The second question concerns defining the appropriate standards surrounding the use of these tests, including patient selection, education, informed consent, test interpretation and counseling.Genetic tests currently move from the research arena, where strategies are put in place to minimize risks,into the clinical context where the practice of medicine is more variable and the risks to patients less understood. In the research setting, risks can be minimized through safeguards including education, consent, and counseling. The frequency and magnitude of psychosocial and clinical risks canbe assessed. In the clinical setting, however, these safeguards may not be used consistently, creating unknown risksfor patients (see table).

This article describes an exercise that teaches students about methodological issues concerned with making reliable observations of behavior. After learning Ekman's (1972) Facial Affect Scoring Technique from a microcomputer program simulating expressions of emotion, students recorded the facial expression, gender, and age of people in natural settings, computed interobserver agreement scores, and submitted a laboratory report. This exercise generated much discussion about research methods, transferred skills from the classroom to a research setting, and illustrated our view that the microcomputer is a new tool that supplements, but does not replace, existing instructional techniques.

Until approximately twenty years ago, advances in the study of human genetics had little influence on the practice of medicine. In the 1980s, this changed dramatically with the mapping of the altered genes that cause cystic fibrosis (CF) and Huntington disease (HD). In just a few years, these discoveries led to DNA-based tests that enabled clinicians to determine whether prospective parents were carriers of CF or whether an individual carried the Huntington gene and, as a result, would almost certainly develop the disease.Observers interested in the social and economic implications of genetic technology realized that such genetic tests could be used by insurance companies to predict which insurance applicants were likely to become ill or even die from these diseases.

Syndromes with lymphatic malformations show phenotypic variability within the same entity, clinical features that overlap between different conditions and allelic as well as locus heterogeneity. The aim of this review is to provide a comprehensive clinical genetic description of lymphatic malformations and the techniques used for their diagnosis, and to propose a flowchart for genetic testing. Literature and database searches were performed to find conditions characterised by lymphatic malformations or the predisposition to lymphedema after surgery, to identify the associated genes and to find the guidelines and genetic tests currently used for the molecular diagnosis of these disorders. This search allowed us to identify several syndromes with lymphatic malformations that are characterised by a great heterogeneity of phenotypes, alleles and loci, and a high frequency of sporadic cases, which may be associated with somatic mutations. For these disorders, we found many diagnostic tests, an absence of harmonic guidelines for molecular diagnosis and well-established clinical guidelines. Targeted sequencing is the preferred method for the molecular diagnosis of lymphatic malformations. These techniques are easy to implement and have a good diagnostic success rates. In addition, they are relatively inexpensive and permit parallel analysis of all known disease-associated genes. The targeted sequencing approach has improved the diagnostic process, giving patients access to better treatment and, potentially, to therapy personalised to their genetic profiles. These new techniques will also facilitate the prenatal and early postnatal diagnosis of congenital lymphatic conditions and the possibility of early intervention.
