Prolonged general anesthesia appears to be safe for children with AADC deficiency undergoing surgery for gene therapy, according to the first case series of its kind. Still, precautions must be taken throughout procedures due to complications associated with general anesthesia in this patient population, including abnormal changes in blood…
The N-Lorem Foundation has partnered with Gondolabio to discover and advance novel antisense oligonucleotide (ASO) treatment options — medications that can correct genetic abnormalities in people — for nano-rare patients, or those with extremely rare diseases. First, the California-based nonprofit will leverage its ASO discovery platform to identify…
Low levels of the nerve signaling molecule dopamine, a feature of aromatic l-amino acid decarboxylase (AADC) deficiency, affect the growth at early stages of nerve fibers in a brain region important for movement, a mouse study reveals. Early nerve fiber growth in AADC-deficient mice lacked the precise guidance seen…
The Energy and Commerce Health subcommittee of the U.S. House of Representatives has voted to advance proposed legislation — several bipartisan bills — to support research into rare disease, including conditions such as aromatic l-amino acid decarboxylase (AADC) deficiency. Among the bills moving forward are two that will encourage…
A 62-year-old woman was found to have acquired aromatic L-amino acid decarboxylase (AADC) deficiency due to a self-directed autoimmune attack, a case study reported. She also had severe orthostatic hypotension, or a drop in blood pressure when standing up, which was successfully treated with vitamin B6 supplements,…
Machine learning, a form of artificial intelligence (AI), was applied to electronic health records to identify young people who may have undiagnosed aromatic l-amino acid decarboxylase (AADC) deficiency, a study reports. Based on a manual review, nearly 23% of the top-ranked predicted cases were…
About one in 10 medications sold in Canada have a patient support program provided by its manufacturer, and nearly half are for rare diseases. That’s according to a study in Canada that also found that patient support programs were offered more commonly for brand-name and expensive drugs. These programs, offered…
A group of international experts in aromatic L-amino acid decarboxylase (AADC) deficiency and similar neurologic conditions have developed guidelines for the safe application of gene therapy in AADC patients, and for needed outcome follow-up. The new recommendations come within a year of approvals in the European Union and the…
Note: This story has been updated May 25, 2023, to state that data from the two children in the report were part of the data package that supported Upstaza’s approval in the European Union and the U.K. The first two aromatic l-amino acid decarboxylase (AADC) deficiency patients older than…
The route of administration now used for the gene therapy Upstaza (eladocagene exuparvovec) — directly into the brain region, called the putamen, that’s affected by aromatic L-amino acid decarboxylase (AADC) deficiency — is better than other modes of delivery, an animal study showed. The other tested routes included…
