it may surprise most people to learn that, although rare diseases by their very name are rare, collectively they affect so many of us. estimates vary, but approximately one in 12 canadians live with a rare disease, or approximately one million people overall. “nowadays, when you talk to people about rare diseases, almost everybody can tell you they know somebody with a rare disease,” says durhane wong-rieger, president and ceo of the canadian organization for rare disorders (cord), which has long been campaigning for the canadian government to improve the way the health-care system identifies, diagnoses, treats and supports rare disease patients.
among the most challenging rare disorders for families is neurofibromatosis (nf), which affects one in every 3,000 births, or approximately 2.5 million people worldwide. nf is a group of genetic disorders that causes benign tumours to grow on nerves throughout the body.
nf affects each patient differently, but it can lead to health conditions and complications including blindness, deafness, bone abnormalities, disfigurement, learning challenges, disabling pain, or cancer.
the various types of nf include nf type 1 (nf1), nf2-related schwannomatosis (nf2), and schwannomatosis (swn)
