LONDON — Charlie Gard, the incurably ill British infant who died on Friday, could not hear, see or even cry. But his case captured the attention of the pope and the United States president, and raised difficult ethical issues that reverberated around the world.

He died with his parents by his side a day after the British High Court ruled that he could be moved to a hospice and that his life support could be withdrawn. His death was confirmed by a family spokesman.

In an emotional statement before the court this week, Charlie’s mother, Connie Yates, noted that her son had “had a greater impact on and touched more people in this world in his 11 months than many people do in a lifetime.”

The infant had a rare and debilitating genetic condition known as mitochondrial DNA depletion syndrome. Charlie, who would have turned a year old on Aug. 4, was not able to peer at his parents’ faces. He also could not swallow.
