MeSH definition : A group of abnormal hemoglobins in which amino acid substitutions take place in either
the alpha or beta chains but near the heme iron. This results in facilitated oxidation
of the hemoglobin to yield excess methemoglobin which leads to cyanosis.;
CISMeF synonym : m, hemoglobin;
MeSH CAS label : hemoglobin M;
Registry Number MeSH : 9083-28-7;
MeSH annotation : an abnorm hemoglobin; /urine: coord IM with HEMOGLOBINURIA (IM); DF: HBM; /urine: coordinate with HEMOGLOBINURIA;
