How does Sanger Sequencing work in this testing process?
Sanger Sequencing is a well-established DNA sequencing method that determines the exact sequence of nucleotides in a specific region of DNA. In this test, the regions containing the known mutations are amplified and then sequenced to identify whether the mutation is present or absent. The process involves labeling DNA fragments, separating them by size, and reading the sequence with high precision. Because of its reliability and accuracy, Sanger sequencing is widely used for mutation confirmation rather than initial discovery. It provides clear and definitive results, which are essential for clinical decision-making.
Who should consider undergoing this test?
This Known Mutation Confirmation by Sanger Sequencing for couples test is suitable for couples who have already identified genetic mutations through prior testing or have a family history of inherited conditions.
