An investigation by 14 European public service broadcasters, including BBC News, has revealed a devastating oversight: sperm from a single donor, who unknowingly carried a deadly cancer-causing gene, was used to conceive nearly 200 children across Europe over 17 years.
The Devastating Impact
- Some children conceived with the sperm have already died from cancer.
- Geneticists estimate that the vast majority of children who inherited the gene will develop cancer in their lifetimes.
- The mutation is in the $TP53$ gene, which, when mutated, causes Li-Fraumeni syndrome.
- This syndrome gives affected individuals a 90% chance of developing various cancers, often starting in childhood, and later in life, breast cancer.
- Up to 20% of the donor's sperm carried the mutated gene, meaning any child conceived with it has the dangerous mutation in every cell of their body.
- Cancer geneticist Clare Turnbull called it a "dreadful diagnosis" that presents a "lifelong burden" for families. One geneticist reported that some children have developed two different cancers and died at a very early age.
The Failure of Screening and Distribution
The donor passed initial screening checks in 2005 when he became a donor at the European Sperm Bank (ESB) as a student.
The discovery was made recently when doctors noticed a cluster of cancers in children linked to sperm donation and raised concerns at the European Society of Human Genetics. Initially, 23 children with the mutation were found among 67 linked to the donor; 10 had already been diagnosed with cancer.
Freedom of Information requests ultimately revealed at least 197 affected children across 14 countries, though the exact number who inherited the mutation is unknown.
The ESB, located in Denmark, sold the donor's sperm to 67 fertility clinics across 14 countries.
- No International Regulation: While nations have domestic limits on how often a donor's sperm can be used, there is no international law restricting global usage.
- Breaches of National Law: In some cases, national laws appear to have been violated. For example, in Belgium, where sperm is limited to six families, 53 children were born to 38 different women using this donor's sperm.
The European Sperm Bank stated it does not ship to the U.S. but does work with banks in Canada and Mexico.
