US EditionEuropean Sperm Donor with Rare TP53 Mutation Linked to 10 Cancer Cases in Children
- In 2024, European researchers identified a sperm donor carrying a rare TP53 gene mutation linked to cancer in at least ten children across eight countries.
- The mutation was uncovered after two families reported childhood cancers, prompting genetic testing of 67 children from 46 families born between 2008 and 2015.
- Twenty-Three children were found to carry the variant, with ten developing cancers such as leukemia and non-Hodgkin lymphoma, conditions associated with Li-Fraumeni syndrome.
- Dr. Kasper explained that back in 2008, detecting this variant would have been nearly impossible, and emphasized that there remain several areas requiring enhancement. He recommended genetic counseling for affected individuals along with regular MRI screenings as part of the follow-up care.
- The case revealed a lack of harmonized European regulation on donor limits and raised calls for continent-wide oversight to prevent similar health risks in the future.
