(October 2008). A genetic disorder is a genetic problem caused by one or more abnormalities in the genome, especially a condition that is present from birth (congenital). Most genetic disorders are quite rare and affect one person in every several thousands or millions. Genetic disorders may or may not be heritable, i.e., passed down from the parents' genes. In non-heritable genetic disorders, defects may be caused by new mutations or changes to the DNA. In such cases, the defect will only be heritable if it occurs in the germ line.
A genetic disorder is a type of disease that occurs when there is some kind of change in the natural makeup of a personâs DNA. This happens when there are different mutations, or damage, in a personâs genes or chromosome lineup.enetic disorders are disorders concerning the DNA that is passed on from parents to their children. While this can be a frightening thing to think about, it is important to learn about the most common examples of genetic disordersso you can find out about treatment and preventive measures.
