DNA tests linked Jacobson to at least 15 such children, and prosecutors charged he may have fathered as many as 75. Jacobson also fooled patients into believing they were pregnant when they were not through hormone treatments that simulated side effects of pregnancy -- then billed them for the conception...

As a result, patients have difficulty breathing, digesting food and even reproducing. "This is a disease that simply wears you down," says Ramsey...

"Presumably the replication error occurs in the sperm or egg before conception," says molecular geneticist Pieter de Jong, who headed the Livermore team...
