The Five Archenemies

aHUS. gMG. HPP. LAL-D. PNH. All five are rare diseases that can challenge your inner strength and that of your family and friends. These five are so rare that they may be misdiagnosed as other more common diseases. With your help, we can unite to spread awareness.


Atypical Hemolytic Uremic Syndrome (aHUS)

An ultra-rare, chronic disease with a high risk of recurrent episodes that progressively damages the kidneys and other organs, potentially leading to sudden kidney failure, stroke, heart attack, and premature death due to clotting and inflammation in small blood vessels.1-4


Generalized Myasthenia Gravis (gMG)

A debilitating, chronic and progressive autoimmune neuromuscular disease that typically begins with weakness in the muscles that control the movements of the eyes and eyelids, and often progresses to the more severe and generalized form, known as gMG with weakness of the head, neck, trunk, limb and respiratory muscles.5,6


Hypophosphatasia (HPP)

A genetic metabolic disease in which bone-building calcium and phosphate cannot mineralize properly, causing problems in the bones, brain, muscles, joints, lungs, and kidneys.7-10


Lysosomal Acid Lipase Deficiency (LAL-D)

A genetic disease that causes a build up of fatty material in vital organs such as the liver, spleen, and intestine, as well as the walls of blood vessels and other tissues.11-14


Paroxysmal Nocturnal Hemoglobinuria (PNH)

A serious disease that destroys the body’s red blood cells, leading to blood clots, kidney damage, fatigue, and lung problems.15-24
