Film explores struggles with rare diseases

There may be only a few thousand people in the United States who suffer from Hermansky-Pudlak syndrome, a disease so rare that most doctors have never even heard of it, much less know how to treat it.

But this very unusual condition is the focus of a documentary airing on public television this weekend, made by two Stanford filmmakers who are trying to draw attention to the plight of patients who suffer from rare diseases.

The documentary “Rare” airs at 6 p.m. Sunday on KQED. For more information about the film, and to see a preview, go to www.rarefilm.org
