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.
The two types of single gene mutations are point mutation, where a single point in the DNA sequence is affected, and FRAMESHIFT MUTATION, where a single gene or nitrogen base â¦ is deleted or added from the mRNA (messenger RNA) sequence causing a shift in the reading frame of the genetic message. gene mutation can be acquired throughout life or it is genetic ex sickle cell anemia chromsome mutations have more pronounced effects and are due to a change in the number â¦ of chromosomes or a change in the structural effect that are inherited..
