Day 37 (2p16.1-2p15): A copper-handling gene discovered using dogs

Day 37 has 34 genes, including COMMD1 (copper metabolism domain containing 1).  This gene helps cells use copper, an essential nutrient used by some enzymes.

COMMD1 was discovered by looking at Bedlington Terriers, a dog breed with a predisposition to copper toxicosis. Because purebred dogs are so genetically similar to each other, figuring out the genetic differences between dogs with and without copper toxicosis was easier than it would have been in humans.
