CRISPR has now genetically cured 3 humans pre-birth. Pretty big deal....
Three people with inherited diseases successfully treated with CRISPR
Two people with beta thalassaemia and one with sickle cell disease no longer require blood transfusions, which are normally used to treat severe forms of these inherited diseases, after their bone marrow stem cells were gene-edited with CRISPR.
Result of the ongoing trial, which is the first to use CRISPR to treat inherited genetic disorders, were announced today at a virtual meeting of the European Hematology Association.
“The preliminary results… demonstrate, in essence, a functional cure for patients with beta thalassaemia and sickle cell disease,” team member Haydar Frangoul at Sarah Cannon Research Institute in Nashville, Tennessee, said in a statement.
Beta thalassaemia and sickle cell are diseases caused by mutations that affect haemoglobin, the protein that carries oxygen in red blood cells. Those with severe forms require regular blood transfusions.
However, a few people with the disease-causing mutations never show any symptoms, because they keep producing fetal haemoglobin in adulthood. Normally, fetal haemoglobin stops being produced soon after birth.
