The Atypical HUS Foundation   Key Info & Resources


NIH GeneReview – Great medical overview of aHUS, with explanations and research links

aHUS occurs with an estimated incidence in the USA of 2 per 1,000,000 (Cited# 57: Maga, Smith at U of Iowa)


aHUS –Potential for Multi-Organ Involvement  (It’s Not Just about Kidney Function)

48% of aHUS patients experience neurological  symptoms  (brain and nervous system),

46% of aHUS patients experience pulmonary symptoms  (lungs),

43% of aHUS patients experience problems with their cardiovascular systems, and about

30% of patients experience complications associated with the digestive system such as an inflamed     colon, abdominal pain, or other issues involving the digestive tract.  FMI, see Alexion’s Patient Materials at


aHUS Bootcamp -  Written by Families, for Families.   This overview is intended as an introduction for newly diagnosed patients and caregivers to begin their journey in the search to become more informed advocates.  Not meant as medical advice nor offering treatment suggestions,  our intent with the aHUS Bootcamp was to give a 'family perspective' and outline basic aHUS areas so that patients and caregivers can participate in more meaningful conversations with their physicians and medical care professionals.

aHUS FAST FACTS      from The Atypical HUS Foundation at

* aHUS affects patients in all age groups.

* Atypical HUS a life threatening disease that affects multiple organs.   Complications of aHUS may include neurological problems, cardiovascular system issues, or complications related to their digestive systems.

* aHUS results from mutations in genes that make proteins to control part of the body's immune system.   It has no cure.  People with aHUS have lifelong risk of sudden, catastrophic  and life threatening complications.

* Uncontrolled complement activation causes blood clots throughout the body's blood vessels.  This clotting process is called TMA or thrombotic microangiopathy.

* When the disease occurs it can result in damage to small blood vessels, yield low red blood cell and platelet counts, and cause damage throughout the body.  Continued aHUS activity can cause vital organs to fail or slowly lose function. 

(NIH GeneReview – See research articles at )

* Atypical HUS  is classified as an ‘ultra-rare’ disease,  affecting less than 20 patients per 1,000,000.  (Ultra-Rare Disease Fact Sheet, Alexion

* Atypical HUS occurs with an estimated incidence in the USA of 2 per 1,000,000 (Maga TKSmith RJ. et al  (  2015 US pop. approx. 320,000,000)  

* 29 Candidates for Complement Inhibitors (PNH).  Dr. A. Risitano, 2014: "The Future of Complement Treatment", Slide 4. European Society for Blood and Marrow Transplantation.


aHUS Alliance

The aHUS Alliance is an international federation of 14 nations dedicated to promoting aHUS advocacy around the world.  Recognizing that aHUS information is continually evolving regarding research, genetics, and orphan drug development, the aHUS Alliance offers aHUS Facts that are an accurate, updated and a dynamic resource.

Click HERE to view learn about world aHUS Awareness Day, marked annually each September 24th.  View the aHUS Alliance global fact sheets.


Rare Disease FAST FACTS    are provided by Eurordis, NORD, and Global Genes .       Global     Rare Disease Day is annually on the last day of February.  JOIN in worldwide advocacy efforts!

There are approximately 7,000 diseases and conditions designated as a rare disease, each affecting fewer than 200,000 Americans.  In Europe, a disease is considered rare if it affects fewer than 1 in 2,000 people.

Rare diseases as a group affect an estimated 25 to 30 million Americans, 1 out of 10 people. Eighty percent of rare diseases are genetic in origin, and it is estimated that about half of all rare diseases affect children.

While more than 300 orphan drugs and biologics have been approved for the treatment of rare diseases by the Food and Drug Administration (FDA), only about 5% of rare diseases have FDA-approved treatment options.  Millions of Americans with rare diseases still have no treatment specific to their disease.

Membership is open to patients, family, friends, caregivers research and medical personnel.


The Atypical HUS Foundation encourages patients and investigators to share information and explore options/resources as we work together to gain insight into this rare complement disorder. By increasing contact opportunities with researchers and medical personnel interested in helping the aHUS community, our stories foster a better understanding of atypical hemolytic uremic syndrome.

Sharing information, inspiration and support for one another, we seek to gather together people and knowledge as we strive to improve the lives of patients and families dealing with a diagnosis of aHUS.

Be proactive! Get the medical basics of aHUS, what lab values to monitor, and areas of concern...check out the "aHUS Bootcamp" and "About aHUS" tabs at the top of this page!
If your doctor has never treated a case of aHUS, please print out our 'Doc to Doc Registry' and ask him/her to contact a physician versed in the complexities of aHUS and new options for 2011 genetic testing and treatment.


NOTE: Our 'Send a Message" function on each Member's page allows for private discussion of personal content. As with any social network, be cautious about giving personal contact information (home email info, phone number) until you have an established relationship with another person, organization, or associated website.


Did you know...

CFH (Serum Complement Factor H) is a regulatory protein. The secreted protein product of CFH consists of 20 repetitive units named "short consensus repeats" or SCRs (each approximately 60 amino acids). In patients with aHUS the last 5 "pearls" in the twenty pearl strand protein, SCR16 - SCR20, should bind to protect cells but do not- they are defective in one or more of the last 5 SCR locations. If they cannot bind or stick to the kidney to protect that tissue, the platelets clump into clots that affect the glomeruli of the kidney -potentially causing acute renal failure.

It is estimated that there are about 2 cases of aHUS in the U.S. per 1,000,000 of population, and about 60% of aHUS patients are diagnosed as children. The condition is potentially life threatening, and either can be chronic or can recur at intervals.
