Sickle cell patient's success with gene editing raises hopes and questions

In London to address a gene-editing summit last week, Victoria Gray took a break to visit Sir John Soane's Museum. In 2019, Gray became the first patient to be treated for sickle cell disease using CRISPR, an experimental gene-editing technique. She was invited to talk about her experiences at the Third International Summit on Human Genome Editing. (Orlando Gili for NPR)

Victoria Gray was wandering through the British Museum in London last week when she spotted a small wooden cross hanging on the wall.

"It's nice seeing all the old artifacts, especially the cross," Gray said. "Religion is something that I hold close to my heart, and my faith is what brought me this far."
