Deletion Mutation: When a segment of a chromosome or DNA sequence is missing or there is a loss of genetic material.

Example: Duchenne Muscular Dystrophy is a form of Muscular Dystrophy that affects 1 in 3,600 boys. This genetic mutation is caused in the dystrophin gene, located on the human X chromosome, which codes for the protein dystrophin and is an important structural component in muscle tissue that provides structural stability to the DCG of the cell membrane.
