The general practitioner and the "new genetics".

GPs are involved in long term care of patients and families with complex conditions. They juggle the need for medical expertise, the relationships between family members, the cost of expertise, limitations of access, and the medicolegal environment. With this background, the GP is ideally placed to play an active role in the "new genetics". GP consultations involving the new genetics will include diagnostic testing for patients with clinical problems, preconception and prenatal testing for couples in relation to pregnancy, predictive testing for families with some genetic conditions, and community genetic screening in some circumstances. GPs will need to understand the language of the new genetics, undergo continuing education, and receive ongoing support to enable them to communicate effectively with patients and their families. Different models of care incorporating GPs, specialists and allied health professionals can be developed to provide maximum delivery of relevant genetic data for both genetic and common multifactorial disorders.
