The biotech firm Editas Medicine says that humans who have had their DNA genetically modified could exist within the next 2 years. The company announced that it will soon start the first trials of what it calls a groundbreaking new technique.
U.S.-based Editas is striving to become the first lab in the world to edit the DNA of patients suffering from leber congenital amaurosis (LCA), a genetic condition that causes
severe vision loss at birth. Some LCA patients also experience central nervous system conditions, such as epilepsy, developmental delays and motor skill impairment.
LCA is said to be caused by defects in a gene responsible for the creation of a protein that is vital to vision. Editas Medicine scientists believe they can fix the mutated DNA using gene-editing technology known as CRISPRs.
CRISPRs, which stands for “clustered regularly interspaced short palindromic repeats,” allows scientists to edit genes “with precision, efficiency and flexibility,” Gizmodo explained in a May 5, 2015 article. Researchers have reportedly been able to create monkeys with targeted mutations and prevent HIV infection in human cells using this piece of biotechnology.
