During a recent visit from another parent whose child has aromatic L-amino acid decarboxylase (AADC) deficiency, a small comment made my wife, Judy, and I pause. “Your house looks like a kid’s gym!” she said with a laugh. We looked around, and she was right. Soft blocks…

When our daughter, Rylae-Ann, was just 3 months old, the first signs of aromatic l-amino acid decarboxylase (AADC) deficiency began to emerge. At the time, we were consumed by only one thought: progress. As the months went by, the absence of progress became painfully clear. The gap between what…
