8-Year-Old Has Disease So Rare It Doesn’t Have a Name. Now, he is the First in the World to Receive Treatment. Amber Freed’s son Maxwell made history in September 2025 when he received treatment for “SLC6A1” thanks to her tireless work and a team of dedicated scientists.
A parent’s determination leads to rare disease treatment for her son: Maxwell Freed, an 8-year-old with the extremely rare neurodevelopmental disorder known as “SLC6A1”, has become the first person in the world to receive a treatment for it, thanks to his mother, Amber Freed, who spent years fundraising and pushing Scientists and Regulators to move the research forward. While a repurposed FDA-approved drug helped buy time early on, her advocacy helped drive the creation and testing of a new gene therapy that received FDA approval in June 2025. Maxwell received the one-time treatment in September 2025 and is now in rehabilitation and showing signs of progress.
