Meet Henry

Henry is a joyful, funny, and resilient 14-year-old who happens to live with Barth syndrome, an ultra-rare, life-threatening genetic disorder affecting only about 300 living individuals worldwide.​
​​
Until September 2025, there were no treatments

But because of this community, that is starting to change.

​​A year that changed everything

In 2025, something extraordinary happened.

After years of advocacy and research, the first-ever treatment for Barth syndrome received FDA accelerated approval. In fact, it was the first approved therapy for any mitochondrial disease.

Together, through Happy Heart, we raised more than $320,000 to help make progress like this possible.

​​But we’re not there yet

That treatment still requires full approval to ensure access for all who need it, and one treatment is not enough.

Families like ours are still waiting for more options, more answers, and more hope.
​
Our work continues until every person with Barth syndrome has the chance not just to live, but to truly thrive.
