What is a genetic disease?
A genetic disease is any disease that is caused by an abnormality in an individual’s entire genetic makeup. The abnormality can range from minuscule to major, from a discrete mutation in a single base in the DNA of a single gene to a large group of chromosomes abnormality involving the addition or subtraction of an entire chromosome or set of chromosomes.
Some genetic disorders are inherited from the parents, while other genetic diseases are caused by acquired changes or mutations in a preexisting gene or group of genes. According to sources at medicinenet.com, mutations can occur either randomly or due to some environmental exposure.
As we unlock the secrets of the human genome, we are learning that nearly all diseases have a genetic component. Some diseases are caused by mutations that are inherited from the parents and are present in an individual at birth. Other diseases are caused by acquired mutations in a gene or group of genes that occur during a person’s life. Such mutations are not inherited from a parent, but occur either randomly or due to some environmental exposure.
This includes many cancers.Most genetic disorders, however, are “multifactorial inheritance disorders,” meaning they are caused by a combination of inherited mutations in multiple genes, often acting together with environmental factors. Examples of such diseases include many commonly-occurring diseases, such as heart disease and diabetes, which are present in many people in different populations around the world. Some specific Genetic diseases are Autism, breast cancer, prostate cancer, Down syndrome, and sickle cell disease.
If we are able to detect what caused these dormant genetically mutated cells to become dominate, then we could use that knowledge to back track and come up with a cure or even a vaccination, so these diseases will become a thing of the past. Many of us have a loved that suffers from a genetic disease, so what would happen if we could prevent and cure the disease while they are still in dormant form.
