Many are clinically harmless and others cause symptoms including microcytosis, sickling disorders, hemolysis, erythrocytosis, cyanosis/hypoxia, long-standing or familial anemia, compensated or episodic anemia, and increased methemoglobin or sulfhemoglobin[mayomedicallaboratories.com]
If the level of blue hemoglobin exceeds 5 g/dL in capillary blood, the clinical result is cyanosis, a bluish discoloration of skin and mucous membranes.[web2.iadfw.net]
Several hemoglobinopathies, designated hemoglobin M variants, closely resemble methemoglobin but have slightly different absorption spectra.1 This group of hemoglobinopathies has an altered oxygen affinity that results in a cyanosis that is usually asymptomatic[zdoc.site]

Without treatment, people with SCD may die in childhood, from problems such as infection. Good treatment makes a great difference. Improvements in treatment mean that life expectancy has increased.[patient.info]

Treatments include blood transfusions and treatment to remove excess iron from the body. If you have mild symptoms or no symptoms, you may not need treatment. In some severe cases, you may need a bone marrow transplant.[icdlist.com]
Continued Treatment With a mild case, you may feel tired and not need treatment. But if it’s more serious, your organs may not get the oxygen they need. You might have to get regular blood transfusions.[webmd.com]
The prognosis of homozygous Hb C disease is excellent. An individual may inherit a Hb S gene from one parent and a Hb C gene from the other. The result of this double whammy is Hb SC disease.[web2.iadfw.net]
