Diagnosing aromatic L-amino acid decarboxylase (AADC) deficiency in newborns is “feasible” using dried blood spots and readily available equipment, allowing for earlier and more effective treatment, researchers report. The study detailing this method, “Detection of 3-o-methyldopa in dried blood spots for neonatal diagnosis of aromatic l-amino-acid decarboxylase…

As anyone affected by a rare disease knows, treating the illness while trying to go about everyday life is an expensive undertaking.  But exactly how expensive — in terms of direct and indirect costs across rare disease populations — might still come as a surprise: almost…

Researchers have developed a patient-derived cell model of aromatic l-amino acid decarboxylase (AADC) deficiency that could provide important insights into the biological underpinnings of the disease, as well as serve as a platform to test potential treatments. The nerve cell model was described in the journal Brain,…

Measuring 3-O-methyldopa (3-OMD) levels in dried blood spots could help in diagnosing aromatic L-amino-acid decarboxylase (AADC) deficiency, a recent study suggests. This approach would be less invasive for patients, who often undergo multiple lumbar punctures before a final diagnosis, and could be used to screen for the disease in newborns.

A new online resource, called AADC Insights, aims to make it easier for healthcare professionals to diagnose and care for people with aromatic l-amino acid decarboxylase (AADC) deficiency. AADC deficiency is an extremely rare condition caused by mutations in the DDC gene, resulting in a lack of a…

Many diseases have their own awareness color — breast cancer is pink, muscular dystrophy is green, and AIDS is red, for example — but what’s the significance of pink, green, blue, and purple lights side-by-side? These are the colors most often used to represent Rare Disease Day. This…

The science behind viral gene therapy — which may hold a potential cure in a single treatment for genetic diseases such as aromatic l-amino acid decarboxylase (AADC) deficiency — was highlighted in a recent review. The study, “Current Clinical Applications of In Vivo Gene Therapy with AAVs,” was…

Diagnosed with sickle cell disease as a 6-month-old, Tristan Lee has faced a lot of challenges over his 37 years of life. But from a young age, he also learned how to turn those trials into triumphs. At age 9, a stroke due to his disease left him paralyzed…

Rare Disease Day at NIH, organized by the National Institutes of Health (NIH) and taking place on March 1, will feature panel discussions, patient stories, research updates, TED-style talks, and a presentation by a Nobel laureate recently recognized for her work on a gene editing tool. The free, virtual…

People with rare disorders have a worse healthcare experience than those affected by chronic diseases, according to the results of an international survey conducted by Eurordis-Rare Diseases Europe. Indeed, rare disease patients overall give their healthcare experience a medium-low rating, of 2.5 on a scale of 1 to 5,…
