Public interest in how genes determine both what we are and what may happen to us is growing. Commercial concerns have promised that they will soon be able to provide us with compact disks containing our complete genetic blueprint. Those people who have pursued their interest down burgeoning websites may have an informed view, but most people (including many doctors) have only a sketchy knowledge of genetics, so any book that sheds a balanced light on current issues is welcome. 

Genetics is just that. Coauthored by two experienced clinical geneticists the book is rooted in clinical practice and has a holistic approach that is noticeably lacking from most published reports of scientific advances. Consisting of a series of papers on key medical, ethical, and social issues about genetics, its topics range from genetic screening in children to the potential use and misuse of genetic information. The background medicine and science are pitched at the right level for general readers, and sensitive and difficult issues are covered well. 


Several chapters emphasise the need to make haste slowly in developing new clinical genetic services. Evaluating their impact needs to be based not only on quantifiable outcomes but also on qualitative assessment of their effect on individuals and their families.

Inevitably, this book does not address all the burning issues in genetics. Keeping abreast of scientific developments and avoiding the hype that surrounds them is a near impossible task, but, as the number of patients seeking advice from genetic centres and their general practitioners increase, it is vital to brush up or acquire at least a basic knowledge of genetics, the potential and limitations of genetic testing, and testing’s possible impact on individuals and society. 

A book such as this helps. Predicting exactly where genetic advances are taking us and how clinical practice will change as a result is difficult. But doctors have little excuse for not understanding the basic issues—to help patients put the hype into perspective and to rationalise the use of overstretched specialist services.
