What genes are related to Dubin-Johnson syndrome?

0

Dubin-Johnson syndrome is caused by mutations in the ABCC2 gene. The ABCC2 gene provides instructions for making a protein called multidrug resistance protein 2 (MRP2). This protein acts as a pump to transport substances out of the liver, kidneys, intestine, or placenta so they can be excreted from the body. For example, MRP2 transports a substance called bilirubin out of liver cells and into bile (a digestive fluid produced by the liver). Bilirubin is produced during the breakdown of old red blood cells and has an orange-yellow tint. ABCC2 gene mutations lead to a version of MRP2 that cannot effectively pump substances out of cells. These mutations particularly affect the transport of bilirubin into bile. As a result, bilirubin accumulates in the body, causing a condition called hyperbilirubinemia. The buildup of bilirubin in the body causes the yellowing of the skin and whites of the eyes seen in people with Dubin-Johnson syndrome. Read more about the ABCC2 gene.
