Long received a bone marrow transplant from the European stranger four years ago — and the unexpected impact it has had on his biology could affect the future of forensic science.
According to a newly published New York Times story, the purpose of the transplant was to treat Long’s acute myeloid leukemia, a type of cancer that prevents the body from producing blood normally.
Following the procedure, the healthy blood-forming cells from the donor replaced Long’s unhealthy cells, allowing his body to resume normal blood production. It makes sense, then, for Long’s blood to contain the DNA of his donor. But Long’s colleague, Renee Romero, who ran the office’s forensics lab, posited that the bone marrow transplant might affect the DNA elsewhere in his body, so she encouraged him to have samples of his DNA collected before the procedure so the team could compare them to after samples.
Long agreed, and since his procedure, the team at the sheriff’s office has collected numerous additional samples of his DNA from various parts of his body.
Sometimes, they find both Long’s DNA and his donor’s in the samples, such as when they test swabs from his lip, cheek, and tongue. Samples of his chest and head hair, meanwhile, show only Long’s DNA.

An associate had a marrow transplant from his brother and something similar occurred.
That’s pretty unexpected.
Unintended consequences. Could it turn him into a soy boy?
This affects using DNA analysis for rape cases.
Long could rape a woman and the semen would incriminate the donor.
My husband died from AML. He also had a bone marrow transplant. I often wondered if that could change his blood type or DNA. This could make a very interesting plot for a mystery movie
Can a white person accept a bone marrow donation from a black person? What would the results of that be?
“Can a white person accept a bone marrow donation from a black person?”
Short answer: yes.
In light of this article, who knows?
The cracker starts to walk with that inimitable ghetto bounce?
How did they get sperm if he had a vasectomy? Cells in the semen would not be sperm, but other somatic cells. These could easily contain donor DNA
And what about kids who are vaccinated with cells from aborted babies? Would a mix of DNA be an issue for the vaccinated kids?
Actually makes sense. Since blood will be going to every living cell in the body, any sample taken from living tissue would contain the donor DNA.
The only way to avoid that result would be to take samples “cell by cell” such that no blood cells are in it.
We’re simply not capable of doing that.
Aliens can though.
What a weird question
Was curious myself, sperm still made, it seems: https://www.mydr.com.au/mens-health/vasectomy-frequently-asked-questions
The sperm would not make it to the semen. If they do the vasectomy was not complete. It can sometimes be reversed, but they tell you not to count on it.
Wrong? Doesn’t the bone marrow donor’s DNA have to “exactly” match the recipients? Well, the closer the better to avoid rejection. Wonder if the donor and the recipient are related?
The only “exact” match would be from an identical twin.
How precise was the post operation DNA test. “Within the margin of error?”
I’ve read that if you have a blood transfusion and take a DNA test within 30 days, your DNA will be a combination of yours and the donors. After 30 days the donor’s DNA will not show up.
My brother had a liver transplant 3 years ago. He asked his doctors about any possible DNA change. The doctor looked kind of puzzled and said, I really don’t know.
