Boy Author Raises $400K for Sick Friend

Dylan Siegel raised $400K to go toward the rare disease his friend has.

Sept. 23, 2013— -- When Dr. David Weinstein heard that a boy named Dylan Siegel was trying to raise money toward the rare liver disease Weinstein studies, he mostly just thought the boy was cute. Dylan was only 6-years-old, after all.

But Dylan's best friend had the rare disease, and he was determined to do something about it.

A year later,Dylan , who is now 7, has raised $400,000 by writing a book called "Chocolate Bar."

As a result, the Global Genes Project, a rare diseases advocacy group, honored Dylan and his best friend, Jonah Pournazarian, with the RARE Champion Award -- which typically goes to grown-ups, Dylan's father, David Siegel, told ABCNews.com.

"Kids can change the world just like any of us," Siegel said.

Jonah has a rare form of glycogen storage disease, a hereditary disorder that means his liver can store sugar but can't release it, causing him to have dangerously low blood sugar levels that can result in seizures or even death.

Jonah has an especially rare form of the disease -- type 1b -- which means he also has a compromised immune system, Weinstein said. Catching a stomach bug from a classmate could land him in the hospital or even kill him.

"This is a disease that affects one in a million people," Weinstein said. "In the United States ... it's probably close to 50 people with type 1b."

So when Dylan found out about his friend's disorder, he went to his parents and told them he wanted to raise money for Jonah, Dylan's father told ABCNews.com.

They thought it was sweet and offered to help him with a bake sale or a lemonade stand.

"He's like 'Don't patronize me. I want to do something big,'" Siegel said with a laugh.

So 24 hours later, Dylan brought them the pages to a book called "Chocolate Bar." He explained that, to him, "chocolate bar" means "awesome." "Disneyland is so chocolate bar," the book starts out. The last page says, "I like to help my friends. That is the biggest chocolate bar."

So the Siegels had 200 copies printed and sold them at a school event. Within a matter of hours, they sold out and made $6,000.

Since then, they've printed more books and even delved into T-shirts, tote bags and cellphone cases. Dylan's goal is to raise $1 million, and he's sure he can do it.

Weinstein said the money is already helping his lab by allowing him to hire additional staff and paying for studies. He's currently studying a gene therapy treatment that has shown promise in curing dogs with glycogen storage disease, and trying to find solutions to other problems that develop as a result of the disease and its treatment.

Even though people come from 38 countries to visit Weinstein's lab, it came within one day of closing for lack of funds. Thanks to Dylan and Jonah, Weinstein said he could stop worrying about funding and work on finding a cure.

"It's making a huge difference," Weinstein said.

Siegel couldn't be more proud.

"When you're 6, you've got grand visions ... all these things just seem attainable," he said. "It's been a blast. ... It validates a 6-year-old's vision of what he thought change could be."
