Gene editing could end HIV, scientists hope, after second patient is 'cured' using rare mutation 

Genetically editing HIV patients to stop the virus attaching to their immune system could be the horizon after a British man was ‘cured’ of the disease using mutated stem cells.

In 2016 a man dubbed ‘The London Patient’ received stem cells from a donor with natural immunity to HIV at Hammersmith Hospital, and yesterday doctors announced he has been free of disease for 18 months.

Natural immunity occurs in some people through a gene mutation which stops the growth of a little docking arm on the outside of white blood cells that allows the HIV virus to grab on.

But transplanting stem cells between strangers is dangerous, requiring patients to undergo chemotherapy to strip away their own immune…
