Genetic changes that are described as de novo (new) mutations can be either hereditary or somatic. In some cases, the mutation occurs in a personâs egg or sperm cell but is not present in any of the personâs other cells. In other cases, the mutation occurs in the fertilized egg shortly after the egg and sperm cells unite.
Mutations can also occur in which nucleotide base pairs are inserted into or deleted from the original gene sequence. This type of gene mutation is dangerous because it alters the template from which amino acids are read. Nonsense Mutation: This type of mutation alters the nucleotide sequence so that a stop codon is coded for in place of an amino acid. 2  A stop codon signals the end of the translation process and stops protein production.
