What is the cost of the Single Mutation Confirmation by Sanger Sequencing – Couple test?
The cost of the Single Mutation Confirmation by Sanger Sequencing – Couple test is approximately ₹17,000, which includes analysis for both partners. This pricing reflects the precision of the technology and the detailed interpretation required for accurate results.
Why is this test recommended for couples instead of individuals?
This Single Mutation Confirmation by Sanger Sequencing – Couple test is recommended for couples because many genetic conditions are inherited, and the risk to offspring depends on whether both partners carry the same mutation. Even if one partner is already known to have a mutation, testing the other partner helps assess the likelihood of transmission. By analyzing both individuals together, healthcare providers can better evaluate genetic compatibility and provide more accurate guidance regarding family planning, reducing uncertainty and enabling informed decisions.
When should a couple consider undergoing this test?
Couples are usually advised to undergo this test when one partner has been identified as carrying a specific mutation through prior genetic screening. It is also recommended when there is a known family history of a genetic disorder or when couples are planning a pregnancy and want to assess potential risks. Additionally, it may be used after prenatal or preimplantation screening suggests a mutation that requires confirmation.
How is the test performed for both partners?
The Single Mutation Confirmation by Sanger Sequencing – Couple test involves collecting blood samples from both individuals. DNA is extracted from each sample, and the specific gene region of interest is amplified using polymerase chain reaction (PCR). Sanger sequencing is then applied to determine the exact DNA sequence in that region. The results from both partners are analyzed and compared to identify whether the mutation is present in one or both individuals. The entire process is conducted in a controlled laboratory setting to ensure accuracy.
What types of mutations can this test confirm?
This Single Mutation Confirmation by Sanger Sequencing – Couple test is designed to confirm specific genetic changes, including single nucleotide variations, small insertions, and deletions. It is particularly effective for verifying point mutations that may have been identified in earlier tests. By focusing on a defined region of DNA, it provides precise confirmation of the mutation and its exact nature.
How accurate is Sanger sequencing for mutation confirmation?
Sanger sequencing is known for its exceptional accuracy in detecting and confirming specific genetic changes. It provides a direct readout of the DNA sequence, minimizing the risk of false results. This high level of precision makes it the preferred method for confirming mutations identified through broader screening techniques.
What does it mean if both partners have the same mutation?
If both partners carry the same mutation, there is a higher risk of passing the condition to their children, particularly in the case of recessive genetic disorders. In such situations, genetic counseling is essential to understand the risks and explore options such as assisted reproductive techniques or genetic screening of embryos.
What if only one partner has the mutation?
If only one partner carries the mutation, the risk of passing on a genetic condition depends on the type of inheritance pattern involved. In many cases, the child may become a carrier but not be affected by the condition. Genetic counseling can help clarify these risks and guide further decisions.
What does a confirmed mutation result indicate for a couple?
A confirmed mutation result indicates that one or both partners carry the specific genetic change being tested. This information is crucial for understanding reproductive risks and planning appropriate medical or reproductive strategies. The results are interpreted in the context of family history and clinical findings.
Is genetic counseling necessary for this test?
