Disease
ABCB6_HUMAN Ocular coloboma;Dyschromatosis universalis;Colobomatous microphthalmia. The disease is caused by mutations affecting the gene represented in this entry. The disease is caused by mutations affecting the gene represented in this entry. ABCB6 mutations are involved in familial pseudohyperkalemia, a dominantly inherited condition characterized by increased serum potassium levels, measured in whole-blood specimens stored at or below room temperature. This condition is not accompanied by clinical symptoms or biological signs except for borderline abnormalities of red cell shape (PubMed:23180570).[1]
Function
ABCB6_HUMAN Binds heme and porphyrins and functions in their ATP-dependent uptake into the mitochondria. Plays a crucial role in heme synthesis.[2] [3]
