Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions. Point mutations are the most common type of gene mutation. Also called a base-pair substitution, this type of mutation changes a single nucleotide base pair.
Types of mutation: 1  Deletions: When parts of a chromosomes are deleted; this means that a section of your DNA is missing. 2  Duplication: When part of a chromosome is repeated; this means there are too many copies of some genes. 3  Insertions: When new base or section of DNA is added to a chromosome.
