The presence of methemoglobin in the blood, resulting in cyanosis. A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait).

Selected genes are highlighted in orange, bookmarked
genes are green
- Chemical increases gene,
- Chemical decreases gene,
- Chemical increases and decreases gene simultaneosly,
No arrows - gene doesn't interact with the chemical.
- Gene should be increased/decreased most of the time and the chemical does it.
- Gene should be increased/decreased most of the time but the chemical does the opposite.
