The researchers noted the case emphasizes the difficulty distinguishing between epileptic episodes, or seizures, and oculogyric crisis — a common symptom of AADC…

RTW Charitable Foundation to Fund Therapy Pipeline for Rare Diseases

The RTW Charitable Foundation will offer grants up to $150,000 per year to develop therapeutics for ultra-rare diseases, including aromatic l-amino acid decarboxylase (AADC) deficiency. The foundation, which supports research that may not have strong commercial backing, provides capital, human resources, and logistical support to help scientists accelerate…

PTC-AADC Gene Therapy Safe, Showing Promise for Children

Using PTC-AADC gene therapy in children with aromatic l-amino acid decarboxylase (AADC) deficiency was found to be relatively safe and led to improvements in motor function, cognitive abilities, and breathing, a review of six clinical trials found. The therapy also showed benefits in feeding, mood, and sleep among…

Italian Expert Panel Issues Diagnostic, Treatment Guidelines

An Italian panel of experts recommends using vitamin B6, dopamine agonists, and monoamine oxidase inhibitors (MAOIs) as first-line therapies for the treatment of people with rare aromatic l-amino acid decarboxylase (AADC) deficiency. Further, the expert panel called for an across-the-board, multidisciplinary approach for follow-up management of patients…

Non-invasive MRI May Help Diagnose AADC Deficiency

Systematic analysis of non-invasive MRI brain scans of people with aromatic l-amino acid decarboxylase (AADC) deficiency identified disease-related changes in brain structure, which may help diagnose the disorder and related conditions, a study suggests. The study, “…
