Cancer-Linked Sperm Donor: Concerns Emerge After Child Cancer Cases
A sperm donor in Europe unknowingly passed on a gene that can cause cancer.
He fathered many children, and some of them have developed cancer.
The donor had a mutation in the TP53 gene, which is linked to a higher chance of cancer.
Doctors are recommending regular health checks for the children who might have inherited the gene.
It highlights the challenges of screening for genetic conditions in sperm donations and the need for careful monitoring of children born from these donations.
The sperm bank has since put limits on how many children a donor can have.
A sperm donor with a cancer-linked gene has fathered at least 67 children.
Ten of the children conceived with his sperm have been diagnosed with cancer.
The donor carried a mutation in the TP53 gene, linked to Li-Fraumeni syndrome.
The sperm was distributed through a Danish sperm bank between 2008 and 2015.
Doctors recommend regular screenings for children who may have inherited the mutation.
