Rethinking evidence for epigenetic inheritance in human research

Area of Science:

• Epigenetics and developmental biology
• Human genetics and heredity

Background:

• Epigenetic inheritance involves passing traits through epigenome modifications, not DNA sequence changes.
• While observed in plants and rodents, human epigenetic inheritance remains unproven due to complex factors.
• Human studies face challenges disentangling environmental, social, genetic, and cultural influences.

Purpose of the Study:

• To clarify concepts and define testable criteria for human epigenetic inheritance research.
• To guide the field from marker identification to rigorous human studies.

Main Methods:

• Conceptual framework development
• Literature review on epigenetic inheritance in humans and other species
• Definition of assessment criteria for human epigenetic inheritance claims

Main Results:

• Identified key challenges in studying human epigenetic inheritance.
• Proposed a framework with clear criteria for assessing epigenetic inheritance in humans.
• Emphasized the need to move beyond marker cataloging to rigorous research.

Conclusions:

• Establishing human epigenetic inheritance requires robust criteria to address biological and methodological complexities.
• The proposed framework aims to facilitate scientifically sound research in this field.
• Further research is needed to validate and apply these criteria for human epigenetic inheritance.
