When Nolin was just three years old he became the first person in the world to be diagnosed with NANS deficiency, a genetic disorder that causes severe neonatal epilepsy, bone abnormalities, and developmental arrest. The problem lies in the body’s inability to make enough sialic acid, a sugar which provides building blocks for many processes in the body.

The diagnosis, made by the clinician-researchers at TIDE-BC, had a profound effect not only on Nolin’s access to care but also in providing support for his parents, Darlene and Frank.

NANS deficiency is a truly devastating condition. Nolin is missing a critical enzyme that affects the development of many of the body’s tissues and cells. As a result, he cannot hold up his head, sit, stand, eat orally, talk or see very well. He needs 24 hours of care, a feeding tube, is prone to airway infections and blood complications, in short, he is completely dependent on others.


Nolin is described along with 8 other individuals with NANS deficiency, a novel inborn error of metabolism, in a recent Nature Genetics article.
