Genetics is a developing field that increasingly influences medical practice in a large number of specialties. This symposium highlighted how current research is providing insights into the genetic causes of disease, leading to a deeper understanding of the pathophysiology and identification of potential novel treatment strategies. We were provided with an overview of developments in monogenic conditions such as Marfan’s syndrome and Duchenne muscular dystrophy and complex traits such as atopic dermatitis. The practicalities of providing genetic testing for more common conditions such as familial hypercholesterolaemia were discussed, highlighting the more prominent role clinical genetics may come to play in mainstream medicine.
