GENE THERAPY:
Panel Reviews Risks of Germ Line Changes
Eliot Marshall
A high-profile experiment using gene therapy to treat hemophilia B has been on hold for 3 months because of concerns that it might alter the inheritable, or "germ line," DNA of patients in the trial. Last week, those concerns got their first public airing at a meeting of the Recombinant DNA Advisory Committee of the National Institutes of Health. The session did not yield a clear decision, but several panel members indicated that they thought the research should be allowed to resume.
