Mutations occur in both germ cells and somatic cells, but the consequences of both are different. Mutations in somatic cells are called somatic mutations. In this case, if mutations occur in somatic cells, they can develop diseases, or start the cancerous process. They give rise to all non-germ line tissues because they do not occur in cells that give rise to gametes.
In addition to this, a process known as teratogenesis may occur, which may end up with congenital defects, disorders, and syndromes. During the process, genetic changes may cause alterations in the baby during the embryonic phase of the pregnancy.<span>
