NPE has become the term for a person who has discovered one or both parents is not genetically related to them, popularized by the first wide-spread NPE support organization, NPE Friends Fellowship. Many people introduce themselves or describe themselves as “I am an NPE” — this serves to connect NPEs and can be a way to help non-NPEs understand how disruptive the late discovery of misattributed parentage can be to someone’s identity.

Research into the experiences of people receiving unexpected results from DNA testing continues.

A new study based at Long Island University aims to explore parental identity experiences in greater depth, from a small number of adults who have taken a DNA test and received an unexpected discovery related to their own parentage.

Research into the experiences of people getting unexpected results from a home DNA test is still in infancy. A new study based at McGill University aims to explore the experiences of consumer DNA testers who receive an unexpected result with implications to their own parentage.
