- According to a recent study by scientists,the world’s first babies whose genes were altered by the Chinese scientists are more likely to die younger.
- In 2018,Chinese scientists had gene-edited the twin babies to knock out a gene called CCR5 in hopes that it would render the babies immune to HIV.
- However,scientists have searched for a repository of human subjects DNA to look for the same variants of the CCR5 that the Chinese scientists gave to the children.
- The scientists have found that the same genome that might grant greater immunity from HIV also makes people vulnerable to dangerous flus and West Nile virus.
- C-C chemokine receptor type 5 which is also known as CCR5 or CD195 is a protein on the surface of white blood cells that is involved in the immune system as it acts as a receptor for chemokines.
- Gene editing is the deliberate alteration of a selected DNA sequence in a living cell.It involves editing an organism’s DNA by altering, removing or adding nucleotides to the genome.
