Overview A genetic mutation is a change to your DNA sequence by removing, adding or replacing pieces of your DNA.

Gene mutations have varying effects on health, depending on where they occur and whether they alter the function of essential proteins. The types of mutations include:

Nov 4, 2021 · There are several types of genetic variants (or mutations). Learn more about the types of variants and how they affect gene function and health.

Apr 29, 2025 · This article will explore the different categories of mutations, the errors during DNA replication that contribute to these changes, and the cellular mechanisms that attempt to repair such …

There are other types of mutations as well, but this short list should give you an idea of the possibilities.

Mutations can be classified in a number of different ways. We will first consider large-scale mutations that affect overall chromosomal structure, and then small-scale mutations that change only one or a …

Dec 19, 2025 · They can be classified by the type of molecular genetic change, whether they're inherited vs. acquired, or if they're dominant vs. recessive.

What are genetic mutations and how do they differ from genetic variations? Genetic mutations refer to changes in the DNA sequence that affect the gene's function, potentially leading to genetic disorders.

They range from small-scale mutations affecting one or only a few bases, to large-scale mutations where whole sections of DNA are changed. Some might have no effect, but others can affect how a …

Dec 4, 2025 · Mutations are of several types. Changes within genes are called point mutations.
