Mutation is a change in DNA, the hereditary material of life. An organism’s DNA impacts how it looks, how it behaves, and its physiology — all aspects of its life. So a change in an organism’s DNA could cause modifications in all features of its life. Once new alleles arise, meiosis and sexual replica mix completely different alleles in new ways to increase genetic variation.

Mutation panels can also be used as first-level diagnostic tests, particularly if the patient is of an ethnicity focused by the panel. They are also applicable for carrier testing of the extended household of a proband, if the familial mutations are on the obtainable panel. ; or there may be a separate genetic defect, presumably for one … Read MoreRead More »
