New dopamine sensor may help diagnose, treat AADC deficiency

Researchers have developed a new sensor to detect dopamine, which may be a useful tool for diagnosing and treating neurological diseases such as aromatic L-amino acid decarboxylase (AADC) deficiency. The sensor was described in the study, “Electrochemical Dopamine Sensing Using Mn-Doped CeO2 Nanomaterial-Modified Carbon Paste Electrode…

AADC deficiency is most common neurotransmitter disorder in study

A new study reports that aromatic L-amino acid decarboxylase (AADC) deficiency was the most common neurotransmitter disorder seen at a clinic in India over the last decade. The study, “Treatable and preventable causes of inborn errors of metabolism: Cohort of neurotransmitter disorders in children from India,” was published…

Girl with AADC deficiency thriving after Kebilidi treatment

Doctors at Boston Children’s Hospital say the gene therapy Kebilidi (eladocagene exuparvovec-tneq) can be life-changing for people with aromatic L-amino acid decarboxylase (AADC) deficiency, as was the case for a girl treated there. When the girl went in for gene therapy treatment as a baby in 2023, she…

Novel research into AADC enzyme may help advance treatment

Scientists created a new cell model of AADC deficiency that has allowed them to understand exactly how two disease-causing mutations in the DDC gene affect the AADC enzyme. According to the team, the new model “is useful to study the molecular basis of the disease.” It “recapitulates some key…
