When it comes to genetic mutations, there can be several terms used to describe a specific type of disturbance. Intragenic mutation, often referred to as point mutation, is a change of a single nucleotide within a gene. It can cause a shift in the amino acid sequence of a protein, which can lead to genetic diseases. If you're looking for a synonym for intragenic mutation, you can use point mutation or gene mutation interchangeably. Other types of mutations include missense mutation, nonsense mutation, frameshift mutation, and more. Regardless of the term, all mutations can have significant impacts on the overall health and wellbeing of an organism.
