Danish sperm donor passes severe genetic disorder to five children
The man, known only as "donor 7042", fathered 43 children, in breach of rules limiting the number to 25, after giving sperm to Copenhagen's Nordisk Cryobank clinic.
But as well as fertilising the clinic's clients, the donor was also transmitting the tumour-producing nerve disorder known as Neurofibromatosis type I (NF1) or Von Recklinghausen's disease.
Parents are considering legal action after it emerged that the sperm bank was told in June 2009 that one of the children born to the donor had been diagnosed with the genetic illness but failed to act.
