Or the gene therapy could work only partially, meaning a fetus with alpha thalassemia that would otherwise have died in the womb instead could survive a few sickly years before dying, Anderson said.

If hemoglobin Barts is detected on a newborn screen, the patient is usually referred for further evaluation since detection of hemoglobin Barts can indicate either one alpha globin gene deletion, making the baby a silent alpha thalassemia carrier, two alpha globin gene deletions ( alpha thalassemia ), or hemoglobin H disease ( three alpha globin gene deletions ).

Anderson wants to inject a healthy gene directly into fetuses during the second trimester of pregnancy to try curing two rare diseases : ADA, which renders the body unable to fight even mild infections and is best known as the " bubble-boy disease "; and alpha thalassemia, a type of anemia that in severe cases kills the baby inside the womb.
