چکیده

We report herein on our observation of recessive congenital methemoglobinemia (type I), an autosomal recessive disorder, in immediate generations (in a mother and her daughter). Molecular analysis revealed a mechanism of inheritance not reported previously, despite the high probability of occurrence in autosomal recessive disorders. This report is also the first publication describing an extremely rare mutation (Arg50Gln) causing this disorder in the Turkish population.

Congenital Methemoglobinemia

Congenital methemoglobinemia is a rare cause of cyanosis. We report a case of a girl, 17 years old with peripheral cyanosis and normal cardio-pulmonary system. She was diagnosed as a case of methemoglobinemia based on findings of polycythemia and HbM band on hemoglobin electrophoresis. We emphasize the importance of this rare entity in the differential diagnosis of cyanosis.

Four New Mutations in the NADH - Cytochrome b 5 Reductase Gene From Patients With Recessive Congenital Methemoglobinemia Type

Recessive congenital methemoglobinemia (RCM) due to NADH-cytochrome b5 reductase (cytblr) deficiency leads to two different types of diseases. In the type I form, cyanosis is the only symptom, and the soluble enzyme is defective in red blood cells. In the type II form, cyanosis is associated with severe mental retardation and neurologic impairment; the enzymatic defect is systemic, involving b...

A novel mutation in the NADH-cytochrome b5 reductase gene of a Chinese patient with recessive congenital methemoglobinemia.

Recessive congenital methemoglobinemia due to nicotinamide adenine dinucleotide (NADH)-cytochrome b5 reductase (b5R) deficiency is classified into 2 clinical types: type 1 (erythrocyte type) and type 2 (generalized type). We found a Chinese family with type 1 recessive congenital methemoglobinemia, the patients from which were diagnosed according to clinical symptoms and b5R enzyme activity in ...

Hereditary Methemoglobinemia Due to Cytochrome b5 Reductase Deficiency

We report a boy with chronic central cyanosis since birth. He was otherwise asymptomatic with chocolate brown color of blood. Methemoglobinemia was suspected after exclusion of the cardiac and pulmonary diseases. Hereditary methemoglobinemia was considered by his clinical course. The simple bedside procedure could be performed to determine methemoglobinemia by vigorous shaking his blood with ox...
