    27. Genetic disease A. What is genetic disorder? A genetic disorder is a disease that is caused by an abnormality in an individual’s DNA. Abnormalities can range from a small mutation in a single gene to the addition or subtraction of an entire chromosome or set of chromosomes.

    41. Genetic disease Single-gene disorders result when a mutation causes the protein product of a single gene to be altered or missing.
