Does Organ Transplant Change Recipient’s DNA?

When discussing organ transplants, a common question arises: does the recipient's DNA change as a result of the surgery? The short answer is no. The genetic makeup of the recipient remains unchanged.

Understanding Organ Transplantation

An organ transplant involves the surgical transfer of a healthy organ from a donor to a recipient who requires one. The donor organ will have a different set of DNA from the recipient, but this does not affect the recipient's genetic material.

The Role of DNA in Organ Transplantation

The donor organ contains its own DNA, which is different from that of the recipient. However, the recipient's cellular DNA does not change during the transplant process. This is because the transplant procedure does not alter the recipient's genetic information; it merely introduces a new organ with its own unique genetic code.

Immune Response and DNA

Following a transplant, the recipient's immune system may recognize the new organ as a foreign entity. This can trigger an immune response, leading to organ rejection. To prevent this, recipients are often prescribed immunosuppressive medications, which help suppress the immune system and reduce the risk of rejection. However, these medications do not alter the recipient's DNA.

Legal Requirements in India

In the context of organ transplants, especially in India, there are stringent legal procedures to ensure the safety and ethical practices of the process.

DNA Testing for Living Organ Donors

India's Transplantation of Human Organs Act 2014 mandates DNA testing for living organ donors to confirm their biological relationship with the recipient. This is to prevent the occurrence of organ rackets or similar fraudulent activities. The DNA tests are performed using the STR profiling method, and the results are submitted to the approval committee. NABL-accredited laboratories are responsible for providing the test reports along with the necessary forms.

Different Types of DNA Profiling for Transplants

Depending on the relationship claimed between the donor and the recipient, different types of DNA profiling tests are conducted:

STR Analysis: General genetic variation analysis to confirm the relationship. Y-STR Analysis: Specific to males, confirming paternal relationships. mtDNA-Based Analysis: Identifying maternal ancestry and confirming close relationships.
