Ehlers-Danlos syndrome
Ehlers-Danlos syndrome affects the collagen gene and prevents the collagen coils from interacting properly. The typical symptoms can range from mild to severe. Mild symptoms would be unexplained abdominal pain, joint hyperactivity, bruising easily, and blood vessels showing through thin skin. Severe would be mitral valve prolapse leading to death. There are no treatments available; therefore, the prognosis for mild variant is survival with behavioral modification and death for severe variant.
Sickle-Cell Anemia
Sickle-Cell Anemia affects the hemoglobin protein and is cause when a substitute of an amino acid in hemoglobin is present. Symptoms include pain in the extremities and/ or organ failure. There are drugs that help treat Sickle-Cell but there is no cure. The prognosis is survival with risk reducing factors but in severe cases death can arise from organ failure.

For Ehlers-Danlos Syndrome, there are six major types. The type I am most familiar with is the Hypermobility Type, formerly known as type III. Hypermobility, known in layman’s terms as being double-jointed, is a particular problem with this type, causing joints to pull partially or full out. According to studies done, this type also has the greatest levels of pain associated with it.
While all types share some similarity, types run true, and it is the Vascular, or type IV, that is the deadly kind, known for causing an aortic aneurysm. The other types do not normally cause death.
There’s a humble two cents for you.
