Mutations and genetic conditions

Genetic conditions are caused by DNA mutations that cause a change in one of the genes affecting the way the body works or develops. These gene variants can then be passed from generation to generation. There are over 5000 different genetic conditions, which together affect over two million people in the UK. Some genetic conditions, like cystic fibrosis and sickle-cell disease, can cause serious health problems for people who inherit them.
