Detailed explanation-1: -Cystic fibrosis is brought about by a point deletion in the CFTR gene, leading to abnormal production of the CFTR protein. Another example of a deletion mutation-related disorder is Turner syndrome, where there is a deletion of the entirety of the X chromosome.
Detailed explanation-2: -(deh-LEE-shun) A type of genetic change that involves the absence of a segment of DNA. It may be as small as a single base but can vary significantly in size.
Detailed explanation-3: -Insertion Mutation Examples For example, some diseases caused by insertional mutations include: Fragile X Syndrome. Huntington’s Disease. Myotonic dystrophy.
Detailed explanation-4: -Such a substitution could: change a codon to one that encodes a different amino acid and cause a small change in the protein produced. For example, sickle cell anemia is caused by a substitution in the beta-hemoglobin gene, which alters a single amino acid in the protein produced.
