He is suffering from the extremely rare Atypical Progeria Syndrome. In fact, he is the only person in the world known to have the condition.Doctors are unsure of how Harry's illness will develop because no one else in the world has it.
The ageing is caused by a genetic mutation and the longest someone with a similar condition has survived is 26.
Harry must take painkillers every day and finds lying in bed painful.
He also has to endure people staring at him in the street.
"I can do a lot of things other children can do, but sometimes it stops me doing what I like doing because I ache," said Harry, who lives with mum Sharon, dad John and sister Emma.
"It feels weird and hurts most when I'm in bed. I get upset when people who don't know me stare and it's annoying going to hospitals."
Harry's mum, Sharon, explained the torture that the family is going through.
She said: "It's just a sit and wait game. Because the change in Harry's gene is unique, they cannot say what's going to happen.
"We have had our tears and the 'why us' moments like every family would have. But we have to remember he is walking, talking and is in mainstream school."

there a rap group based out of south africa where one of the members has progeria. he's gotta be at least 25, but he looks like he's a 300 year old hobbit reject.
NOT the only person in the world with Progeria! LOOK UP: Leon Botha. He's the DJ for that South African rap group. Born in 1985, making him the oldest Progeria survivor. Maybe those dumbass doctors should do some fucking research
NOT THE ONLY PERSON IN THE WORLD WITH PROGERIA!!!! LOOK UP: LEON BOTHA!!!!!

Hey idiots! Maybe you should read the article more clearly. The article did not say he's the only one with Progeria, and in fact mentioned the oldest survivor of progeria was 26 years old at death.
This article is saying that this boy is the only boy in the world with ATYPICAL progeria. Look at his face; it definitely is not typical to others with progeria. His condition is also progressing differently.
Maybe you Afrikaaner bitches need to learn how to read a little better!
for all of the idiots who posted on this without paying attention, he was not said to be the only person with Progeria, merely the only one with that type of progeria. please read the article and know what your talking about before you start saying stupid things. sad story
