Years ago, my wife, Judy, and I received the news that our daughter’s clinical trial application had been approved, allowing her to receive an experimental therapy for her rare and life-threatening disease, aromatic l-amino acid decarboxylase (AADC) deficiency. As our cheers subsided, questions began to fill the air.
The Journey of Beautiful Destinations — Richard E. Poulin III

Richard E. Poulin III is an American currently working as Head of Middle School for an international school in Bangkok, Thailand. He is also the president of the nonprofit organization Teach RARE. In 2018 his newborn daughter, Rylae-Ann, was diagnosed with the ultra-rare disease, aromatic l-amino acid decarboxylase deficiency. Richard shares his journey and aims to provide caregivers with strategies and tips to improve their family’s journey.
When our daughter, Rylae-Ann, first walked into a classroom at a private international school in Thailand, it felt like a moment we once thought might never come. Rylae-Ann was born with aromatic l-amino acid decarboxylase (AADC) deficiency. This rare genetic disorder affects the body’s ability to produce…

Instead of asking what’s the matter with my child, ask what matters to my child. What do I need for them to be happy and successful? After our daughter, Rylae-Ann, was diagnosed with aromatic l-amino acid decarboxylase (AADC) deficiency, the traditional milestones by age went out the window.
It took years of persuading our daughter, Rylae-Ann, to hop into the curved seat of the playground swing on her own and enjoy the freedom and weightlessness of swinging. When she turned 5 in April, we filmed and shared this significant achievement with family and friends after she finally…
As a child, I hated expecting the same old routine. The best days were when something unexpected happened. Excitement and thrill induced wonderful feelings and were seared into my memory. Those are still the standout moments for me when I reminisce about my youth. As an educator, I now know…
Parenting is already a full-time job, but the list of tasks mounts for parents of children with health challenges. After work during the week and on weekends, my wife and I operate as a team to coordinate our 5-year-old daughter Rylae-Ann’s care and therapy sessions, as she…
Before my daughter, Rylae-Ann, was diagnosed with aromatic l-amino acid decarboxylase (AADC) deficiency, I had no idea about the size and scope of the rare disease community. When I entered this new world, information and resources were difficult to find. But the power of celebrities and other public…
When our daughter, Rylae-Ann, was 18 months old, my wife, Judy, and I learned she had a rare disease known as aromatic l-amino acid decarboxylase (AADC) deficiency. As of 2020, only about 135 cases of AADC deficiency had been described worldwide. Thankfully, though, a vast network…
My wife, Judy, and I had stayed up late for meetings and written papers advocating for the approval of Upstaza (eladocagene exuparvovec), so we celebrated when the news was finally made public. In November, the gene therapy formerly known as PTC-AADC was approved in the U.K. to treat…
Some may think it’s all right or even supportive to temporarily take a group of struggling students out of the classroom for focused intervention. In all of the schools where I’ve worked, students were pulled out of their general education environment and sent to a room with…
Two parents, unbeknownst to them, were carriers of a rare disease. They were shocked to learn about this genetic fluke after their child was born. From that moment on, life changed for the family, but together, they were able to create a meaningful journey. Sound familiar?…
As a baby, our daughter, Rylae-Ann, had very poor muscle tone. It was barely enough to sustain her body. When she began missing her milestones, the importance of movement became apparent to my wife, Judy, and me. Rylae-Ann was born with the rare disease aromatic l-amino acid…
When my daughter, Rylae-Ann, was born, my wife, Judy, and I celebrated as all new parents do. We took photos and showed her off to family and friends. The excitement focused our attention on what was right. Years later, we realized noticeable symptoms were present after we learned she…
