Summaries for ABCB6 Gene

Entrez Gene Summary for ABCB6 Gene

  • The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance as well as antigen presentation. This half-transporter likely plays a role in mitochondrial function. Localized to 2q26, this gene is considered a candidate gene for lethal neonatal metabolic syndrome, a disorder of mitochondrial function. [provided by RefSeq, Jul 2008]

GeneCards Summary for ABCB6 Gene

ABCB6 (ATP-Binding Cassette, Sub-Family B (MDR/TAP), Member 6 (Langereis Blood Group)) is a Protein Coding gene. Diseases associated with ABCB6 include microphthalmia, isolated, with coloboma 7 and dyschromatosis universalis hereditaria 3. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and ABC-family proteins mediated transport. GO annotations related to this gene include heme binding and efflux transmembrane transporter activity. An important paralog of this gene is ABCB7.

Polymorphic Variants from UniProtKB/Swiss-Prot for ABCB6 Gene

Genetic variations in ABCB6 define the Langereis blood group system (LAN) [MIM:111600]. Individuals with Lan(-) blood group lack the Lan antigen on their red blood cells. These individuals may have anti-Lan antibodies in their serum, which can cause transfusion reactions or hemolytic disease of the fetus or newborn. The Lan(-) blood group is only clinically significant in transfusion settings or during pregnancy; otherwise Lan(-) individuals have no clinical features

Disorders for ABCB6 Gene

(3) OMIM Diseases for ABCB6 Gene (605452)


  • Microphthalmia, isolated, with coloboma, 7 (MCOPCB7) [MIM:614497]: A disorder of eye formation, ranging from small size of a single eye to complete bilateral absence of ocular tissues. Ocular abnormalities like opacities of the cornea and lens, scaring of the retina and choroid, and other abnormalities may also be present. Ocular colobomas are a set of malformations resulting from abnormal morphogenesis of the optic cup and stalk, and the fusion of the fetal fissure (optic fissure). {ECO:0000269 PubMed:22226084}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Dyschromatosis universalis hereditaria 3 (DUH3) [MIM:615402]: An autosomal dominant pigmentary genodermatosis characterized by a mixture of hyperpigmented and hypopigmented macules distributed randomly over the body, that appear in infancy or early childhood. The trunk and extremities are the dominant sites of abnormal pigmentation. Facial lesions can be seen in 50% of affected individuals, but involvement of palms and soles is unusual. Abnormalities of hair and nails have also been reported. Dyschromatosis universalis hereditaria may be associated with abnormalities of dermal connective tissue, nerve tissue, or other systemic complications. {ECO:0000269 PubMed:23519333, ECO:0000269 PubMed:24224009, ECO:0000269 PubMed:24498303}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Note=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). {ECO:0000269 PubMed:23180570}.
