Can Organ Transplants Change Your DNA
“can an organ transplant change DNA”
Summary
An organ transplant can introduce donor DNA that appears in the recipient’s bloodstream and some tissues, creating a state of DNA chimerism, but it does not alter the recipient’s own cellular genome. The recipient’s DNA in most of their cells remains unchanged, even though donor DNA may be detectable in blood or immune cells.

In addition, warm and cold ischemia as well as immune rejection of the transplanted organ or tissue bring about destructive changes in the graft parenchymatous cells. The knowledge of the fate of donor DNA distributed in passenger cells and in fragments of disrupted nuclei as well as the role of recipient cells internalizing donor DNA could give some insight into the mechanism of graft destruction and immunization or tolerance to donor antigens.

The high levels of donor DNA at the time of heart rejection were inversely proportional to the concentration of donor passenger cells detected with use of flow cytometry. Depending on the type of graft, the kinetics of DNA distribution in recipient ...

The APOL1 variants, for example, predict graft failure and have been implicated in liver necrosis in mouse studies, but were found to have only a small effect on outcomes after liver transplantation.69,70 Moving to other types of organ transplantation and other ancestral groups will be essential in gaining a full comprehension of transplantation outcomes and their molecular pathways. Studies have started to address the “genomic collision” hypothesis which states that the risk of rejection may be increased in recipients homozygous for loss-of-function variants with grafts from nonhomozygous donors.

- Using DNA Sequencing to Monitor Organ Transplant Rejection
Because donor DNA can be detected earlier than other rejections signals, physicians might use that information to increase immune suppression to get ahead of a rejection event before it happens, keeping both the transplanted organ and the patient recipient healthier.

The recipient's DNA does no change, but after the transplant, the recipient will have two sets of DNA in their body: their own DNA is found in most of their cells, and the donor’s DNA is found in their blood and immune system cells.
