Clinical genetics
Clinical genetics is an ever-growing encyclopedia of knowledge and new discoveries. This chapter summarizes clinical genetics for the general paediatrician. Included are how to take a genetic history, features pointing towards an underlying genetic problem, when and how to investigate for genetic conditions, the main tests that are used, and an overview of some of the more commonly encountered conditions. A key point to consider is that genetic investigations are fraught with interpretation challenges. If investigations are sent inappropriately or not enough clinical information is given with the request form, then ambiguous results are not uncommon, creating further worry for both patient and clinician. If in doubt, seek expert advice from your local clinical genetics service.
