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.
Non-infectious diseases (also called Non-communicable diseases) are those diseases that are not caused by a pathogen and cannot be shared from one person to another. Non-infectious diseases may be caused by either the environment, nutritional deficiencies, lifestyle choices, or genetic inheritances.enetic disorders are caused by errors in genetic information that produce diseases in the affected people. These errors may include: A change in the chromosome numbers, such as Down syndrome A defect in a single gene caused by mutation, such as Cystic Fibrosis. Environmental disease is a very broad category.
