WebInsufficient protein can be caused by several mutations, including missense and splice mutations. As mentioned above, some splice mutations interfere with the way the cell reads the DNA instructions for making a protein. This can result in a limited quantity of normal CFTR protein reaching the cell surface, which results in residual function.

In 1959 Ernst Freese coined the terms "transitions" or "transversions" to categorize different types of point mutations.
