Scientists reporting in the New England Journal of Medicine report that three genes will offer new understanding to multiple sclerosis and may lead to new treatments. Skeptics among us will be forgiven for remembering that scientists had the same idea half a century ago, after French geneticist Jerome Lejeune identified the triple 21st chromosome in Trisomy 21 (Down syndrome). And have new treatments for Down syndrome materialized? Nope. There are, however, lots of very profitable prenatal screens and tests that are widely used to prevent the births of infants with Down syndrome.
