Experts have said that while Arturo and Charlie have similar conditions they can't be compared because they
are different mutations. Arturo's dad said this is no reason not to try.
"Charlie is writing the books for his mutation just like my son did for his," he said.
"With all due respect to those doctors, because I'm only a father I'm not a doctor, they perhaps are unaware
of the extraordinary medications.
"Even though they are experimental, these are clinicians and medical doctors that are specialists in
mitochondrial conditions and they are hopeful and they believe that these medications will work for Charlie Gard."
Art has been to the UK to meet Charlie and his parents, Connie and Chris, and has kept in touch with them
throughout their battle.
"I speak to Connie often. Even though we are separated by an ocean - we are one family."
Arturo couldn't wait for our interview to be over so he could get outside in his wheelchair into the sunshine.
He loves being near the water. He told his mum, Olga, he wants a fishing rod.
He also loves dogs and The Lion King. Overall he is able to experience joy and a quality of life his parents
didn't dare to dream of a few years ago.
But there is no guarantee that Charlie would respond in the same way.
These parents - who have faced unimaginable challenges - want their friends across the sea to have at least
the same chance they did.
