26-Year-Old Mother’s DNA Did Not Match With Her Kids For A Reason That Sent Ripples Through The Science Community

A Rare Case

Lydia and Karen both have a rare case of a genetic syndrome called Chimerism. Chimerism is a condition which initiates right from the womb when a baby is conceived. In the womb, people with Chimerism begin as twins. But during the early stages of pregnancy, one of the twins absorbs the other. This happens way before a woman even comes to now she has twins in her womb.
