Scientists hunt for hidden genes behind rare pregnancy moles
NCT ID NCT01008501
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to find the genetic changes that cause some women to have repeated molar pregnancies (abnormal growths in the womb). Researchers will analyze DNA from blood and tissue samples of up to 100 women and their relatives. The goal is to discover new genes linked to this rare condition and other unexplained pregnancy losses.
