Only The DNA in her thyroid nodule matched her kids

Her kids’ DNA was found in her thyroid nodule. It was only evident in a part of her that nobody would have suspected. This case seemed very similar to Lydia Fairchild’s case, where there were no links of her children’s DNA in her body.

It turned out a medical phenomenon called “chimerism”

In the medical world, this phenomenon is known as “chimerism.” There are situations when one of the fertilized eggs absorbs the other. In this case, there are two sets of genetic codes in a single egg in the resulting union of the fused eggs.

Attorney Tindell, who became Fairchild’s lawyer, was reading the New England Journal of Medicine when he came across the case. He then requested the court for more time so that they could have Fairchild do the same tests.

Fairchild was ultimately proved as their biological mother

After doing all the tests, they established rather quickly that Fairchild was, in fact, their biological mother. It turns out the story was the same story for both Lydia Fairchild and Karen Keegan. “I probably wouldn’t have my kids today if they didn’t discover her situation. They wouldn’t have known to even consider me as a chimera,” Fairchild explained. So the mystery of Fairchild’s case may be solved, but the mystery of ‘chimerism’ still remains an unanswered question.
