gene mutation
Hereditary code change
A gene mutation is a permanent change in the DNA sequence that makes up a gene, differing from the sequence found in most people.
Mutations can range from a single nucleotide substitution to large deletions or insertions of genetic material.
Some mutations cause disease or increase disease risk, while others are harmless or even beneficial.
The gene mutation responsible for sickle cell anemia affects hemoglobin production.
Mutations may be inherited from parents or occur spontaneously during cell division.
