Many diseases have a well-characterised genetic basis, while others are multifactorial with a genetic component. This course will give you an opportunity to explore genetic disease, the types of mutations leading to disease, and the consequences for treatment. Genetic analysis forms an important tool for the clinician, and developing parallel bioinformatics tools will lead to more effective personalised treatments. A further important aspect of medical genetics is the provision of evidence and advice for the genetic counsellor. The molecular revolution will continue well into this century and the number of effective genetic treatments will increase – so be well prepared to take part.
