Molecular clues to imprinting problems after fertility treatments
Identifying Molecular Signatures of Genomic Imprinting Errors
This project looks for molecular clues that explain why fertility treatments can sometimes lead to imprinting problems in babies.

What this research studies
This work focuses on how assisted reproductive technologies (ART) may disrupt imprinting, the DNA marks that regulate key growth and development genes. Researchers will study eggs and very early embryos to see whether maternal molecules and common ART procedures affect DNA methylation at imprinted genes. The team will use laboratory models guided by observations from children with imprinting disorders linked to ART, such as Beckwith‑Wiedemann and Angelman syndromes. The aim is to identify molecular signatures that could help detect or prevent imprinting errors associated with fertility treatments.
Who could benefit from this research
Good fit: Families who have used or plan to use ART and parents or children affected by known imprinting disorders would be most relevant for related sample donation or follow-up studies.
Not a fit: People seeking immediate infertility treatments or those with conditions unrelated to imprinting changes are unlikely to receive direct benefits from this basic research.
Why it matters
Potential benefit: If successful, the project could lead to tests or changes in fertility practices that reduce imprinting errors and lower the risk of imprinting-related disorders.
How similar studies have performed: Previous animal studies have shown that ART procedures can cause imprinting methylation errors, but translating those findings into human prevention strategies is still at an early stage.
