Genetic mutations can arise in many forms within germ-line and somatic cells, and commonly lead to disease. Mutations can be located within introns and exons, and when present in the intron-exon boundary can affect splicing. Missense and nonsense mutations, as well as insertions and deletions are all important genetic mutations that can be targeted and analyzed using Retrogen's Mutation Analysis Service.
When a single nucleic acid substitution is made, causing translation of a different amino acid, the mutation is considered Missense. Not all missense mutations have detrimental effects on their resulting proteins, for example if an amino acid is changed to another with similar chemistry, or if the change is made in a non-active site that doesn't also affect the structure, then these could also be classified as a "silent" mutation.
A non-sense mutation occurs when a point mutation results in a stop-codon anywhere within the open reading frame, resulting in a truncated poly-peptide, which usually isn't functional.
Insertions and Deletions (Indels)
Insertions occur when any number of nucleotides are added into a sequence, and a deletion is the opposite case, where there has been a loss of nucleotides in the sequence. Collectively referred to as "Indels," they can be a cause of frame-shift mutations when the change in nucleotides doesn't occur in multiples of three.
