Which type of mutation is responsible for many single-gene genetic disorders?

Question

Quizplus · Accepted Answer

Point mutations are responsible for many single-gene genetic disorders. This type of mutation involves a change in a single nucleotide (A, T, C, or G) in the DNA sequence, such as a substitution, insertion, or deletion. These mutations can disrupt the normal function of a gene or protein, leading to genetic disorders. Examples of single-gene disorders caused by point mutations include cystic fibrosis and sickle cell anemia. Copy number variations and nucleotide repeat expansions are types of mutations that can also cause genetic disorders, but they typically involve changes in larger portions of the DNA sequence. Single nucleotide polymorphisms (SNPs) are common variations in the DNA sequence that are not typically associated with genetic disorders.
