DNA DISCOVERY & NPE VOCABULARY GUIDE

Terminology

We have found that common NPE and DNA discovery terms generally fall into three main categories:

Identity

CORE RELATIONAL TERMS
⏷

Emotional

MENTAL HEALTH IMPACT TERMS
⏷

Scientific

GENETIC CONCEPTS TERMS
⏷

Core Identity & Relational Terms

  • Not Parent Expected

    A person who discovers (or receives confirmation) through DNA testing that one or both presumed parents are not biologically related.

  • Misattributed Parental Experience

    Umbrella term for NPEs, donor-conceived individuals, and late-discovery adoptees.

  • Donor-Conceived Person

  • Late-Discovery Adoptee

    A person who learns later in life that they were adopted.

  • Late-Discovery Donor-Conceived Person.

  • Biological father or mother.

  • The family into which someone was born or raised. May differ from biological family in NPE cases.

  • A change in perceived family roles and relationships following DNA revelations.

  • Whether someone chooses to engage or disengage with biological relatives.

  • Sharing one’s NPE status or genetic truth with others.

Mental Health & Emotional Impact

  • A disruption in one’s sense of self triggered by unexpected genetic revelations.

  • The psychological impact of learning unexpected biological truths.

    (Developed by Dr. Paulette Bethel))

  • Confusion and emotional disorientation following a DNA surprise.

  • Emotional injury from broken or misrepresented bonds with caregivers or family.

  • Prolonged or intensified grief, often due to ambiguous or disenfranchised loss.

  • Grief that is not socially recognized or validated.

  • Breakdown in trust or connection within family systems.

  • A unit of measurement estimating shared DNA between individuals.

  • A portion of DNA shared between two individuals.

  • Ancestral breakdown based on genetic markers—subject to algorithm changes.

  • A person identified through DNA testing as biologically related.

  • Combining DNA testing with traditional genealogy to uncover relationships.

  • NPE

    A genealogical term for a break in expected paternal lineage.

  • Alternative terms for misattributed paternity.

  • Twins conceived with two different fathers.

  • GC
