The Genetics of Disease

The genetics of disease involves studying how our genes, which are made of DNA, influence our health. Some diseases are caused by inherited gene mutations passed down from parents, increasing the risk of conditions like cystic fibrosis or certain cancers. Others result from new mutations or changes in genes that happen during a person's life. Environmental factors, such as diet or exposure to toxins, can also interact with our genetics to affect disease development. Understanding these genetic factors helps in prevention, diagnosis, and personalized treatments tailored to an individual's genetic makeup.
