Definition of «small deletions»

Small deletions refer to a type of genetic mutation where a small portion of DNA is removed or deleted from a specific location on a chromosome. This can occur due to errors during cell division, exposure to certain chemicals or radiation, or other factors that cause damage to the DNA molecule. Small deletions may not always be detrimental to an organism's health, but they can sometimes lead to genetic disorders or diseases if the deleted portion of DNA contains important genes or regulatory elements.
