Gilbert's syndrome is due to a genetic mutation that causes only 30% of the enzyme UGT1A1 to be produced. This is the only enzyme that detoxifies bilirubin, a toxic product of the natural breakdown of red blood cells. This enzymatic shortage leads to an excess of bilirubin (and other toxins) in the blood serum. Most people with Gilbert's Syndrome also have linked mutations in two other enzymes - UGT1A6 and UGT1A7, causing similar enzyme shortages which leads to their related toxins circulating in the body for longer periods as well.
