NPE stands for Non-Paternal Event.
It is a term used in the DNA and genetic genealogy communities to describe a discovery that the father someone believed was their biological parent is not their biological father.
Many people learn this unexpectedly through ancestry DNA testing services such as AncestryDNA, 23andMe, or other genetic genealogy tools.
People who discover through DNA testing that the father they believed was their biological parent is not often describe the experience as an emotional earthquake.
Shock, confusion, anger, grief, curiosity, numbness, and disbelief can all appear, sometimes shifting hour by hour.
