Meanwhile, genetic carrier tests are more accurate because scientists know more about single gene disorders, such as Huntington's disease and sickle cell anemia, Faucett said.

Moreover, while the patient base for Duchenne may be too small to spark a billion-dollar drug, the PTC chemical could work against similar underlying gene flaws in other disorders such as cystic fibrosis, hemophilia and spinal muscular atrophy.

More than 6, 000 of these disorders are rare diseases, most of them caused by a single gene, and fewer than 200 have a drug treatment available.
