ATP-binding cassette sub-family G member 5

ABCG5 gene is localized in a head-to-head position with the ABCG8 gene. Both use the same promotor and encode proteins with similar function, which is excretion of plant-derived cholesterol-like molecules, such as sitosterol into the bile duct and bowel. Mutations cause autosomal recessive sitosterolemia and mediterranean macrothrombocytopenia.
