Examples of frameshift mutation diseases
WebA frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read. The shift in the reading frame is … Several diseases have frameshift mutations as at least part of the cause. Knowing prevalent mutations can also aid in the diagnosis of the disease. Currently there are attempts to use frameshift mutations beneficially in the treatment of diseases, changing the reading frame of the amino acids.
