Welcome to the website for the PNH (Paroxysmal Nocturnal Hemoglobinuria) support group. Although there is an abundance of resources on this site, our aim is not to inundate the reader with medical information, but to provide support and to share the personal experiences of the members who are afflicted with, or care about someone with this condition.

We are not medical specialists, but due to the rarity of the disease, the combined knowledge of our 400+ members is a huge benefit to all who join our group. If you have recently been diagnosed with PNH, or know someone who has, this group is a wonderful source of information.

Our members area has lots of information available and there is no need to register for an account if you don’t want to. Feel free to read the Frequently Asked Questions, check out the medical terms in the Glossary, or access medical articles in the Files section. There is also an abundance of Web Links to other sites with information about PNH.
