Changes in many genes, each with a small effect, may underlie susceptibility to many common diseases, including cancer, obesity, diabetes, heart disease, and mental illness. In people with a genetic predisposition, the risk of disease can depend on multiple factors in addition to an identified genetic change.These include other genetic factors (sometimes called modifiers) as well as lifestyle and environmental factors.he World Health Organization offers information about genetic predisposition to several common diseases, including cancer, diabetes, cardiovascular disease, and asthma. Genetic Alliance UK offers a fact sheet on genetic predisposition to common genetic diseases.
A disease is an abnormal condition affecting the body of an organism. There are four main types of disease: pathogenic disease, deficiency disease, hereditary disease, and physiological disease.Pathogenic diseases are caused by what is called a pathogen. Pathogens are parasitic organisms that cause disease in their host.For example the pathogen e.coli which can make people ill or kill them. Deficiency diseases are caused by a deficiency of a particular nutrient in the diet.A lack of vitamin c causes scurvy. Hereditary diseases are passed on through generations via their genes, for example sickle cell disease.hysiological diseases such as diabetes can be treated by: Diet-a healthy diet is key to controlling blood sugar levels and preventing diabetes complications. Exercise-regular exercise can reduce the risk of developing complications of diabetes such as stroke and kidney failure.
