The rarest diseases known to man are Fibrodysplasia Ossificans Progressiva, Pseudomyxoma Peritonei and RPI Deficiency.
Pseudomyxoma Peritonei is a rare cancer of the appendix that affects around 2 people per million people each year.
Fibrodysplasia Ossificans Progressiva is a genetic condition that causes a second skeleton to grow over the first and there are fewer than 800 known cases worldwide.
RPI deficiency is considered the rarest disease in the world and only one case was diagnosed in 1984 and it affects the body's metabolic process and can cause seizures, brain white matter reduction and muscle stiffness.
Ultra rare disease is a disease that affects less than 1 in 50,000 people which means in the United States fewer than 7,000 people live with an ultra rare disease and some diseases are so rare that only a few people worldwide have them.
An example of an ultra rare disease is Ribose-5-Phosphate Isomerase (RPI) which is a crucial enzyme in a metabolic process in the human body and the condition can cause seizures, reduction of white matter in the brain and muscle stiffness.
