The world’s biggest gathering of rare disease researchers, patient groups, pharmaceutical executives, and government officials is planned for April 10–12 in a Washington, D.C., suburb. Some 1,200 people have already registered to attend the World Orphan Drug Congress (WODC) USA 2019, set to take place at the Gaylord National Harbor…

About 100 scientists, researchers, pharmaceutical executives, and others will converge on Austria’s capital city early next month for the 2nd International Congress on Advanced Treatments in Rare Diseases. The March 4-5 meeting, to take place at the Hilton Am Stadtpark Vienna, features 27 speakers on a variety of disorders…

Only 18 months after its initial licensing, Agilis Biotherapeutics‘ gene therapy for aromatic l-amino acid decarboxylase (AADC) deficiency has been deemed ready for submission to the U.S. Food and Drug Administration (FDA). Given its rare disease status, with roughly 120 cases of AADC deficiency described to date, this is a “remarkable…

Microstructural changes were observed in brain regions related to language and motor function in children with aromatic L-amino acid decarboxylase (AADC) deficiency, suggesting that this enzyme shortage can influence brain development, researchers have found. Their study, “Microstructural Changes of Brain in Patients with Aromatic L-Amino Acid…

A gene therapy consisting of a viral vector carrying the DDC gene improved motor and cognitive functions in children with AADC deficiency, according to a Phase 1/2 trial. The study, “Gene therapy improves motor and mental function of aromatic l-amino acid decarboxylase deficiency,” was published in Brain.

The U.S. Food and Drug Administration (FDA) is updating its 2015 draft guidelines for drug discovery in rare diseases, with new guidance on natural history — how disorders such as spinal muscle atrophy (SMA) run their course if untreated — the choice of “efficacy endpoints” in clinical…

A mouse model of aromatic l-amino acid decarboxylase (AADC) deficiency, carrying a frequent mutation in patients with the condition, has been developed for the first time, according to researchers. Findings from this new model indicate that low levels of the neurotransmitter serotonin are associated with characteristic symptoms. The study, “…

The International Working Group on Neurotransmitter Related Disorders (iNTD) has created guidelines for the care of patients with aromatic L-amino acid decarboxylase (AADC) deficiency. Titled, “Consensus guideline for the diagnosis and treatment of aromatic l-amino acid decarboxylase (AADC) deficiency,” the guidelines were published in Orphanet Journal of…
