Abnormal hemoglobin: Methhemoglobin is an abnormal form of hemoglobin, usually due to oxidative damage. Some inherited forms of hemoglobins are more susceptible to such damage and could be said to be due to gene disorder.

Methemoglobinemia: Methemoglobinemia is called "blue man disease" because blood has a blue tint (instead of red) due to methemoglobin. It can be caused by ingestion of certain drugs or compounds. A genetic form is due to nadh-cytochrome b5 reductase deficiency (an enzyme) which causes decreased oxygen carrying capacity of the blood, with resultant cyanosis (=blueness) and hypoxia (low oxygen in blood).
