Quizplus · Accepted Answer

Phenylketonuria (PKU) is a genetic disorder that involves a malfunctioning enzyme that prevents the metabolism of phenylalanine, an amino acid found in many foods. This results in the buildup of phenylalanine in the blood and brain, causing intellectual disability and emotional disturbance if left untreated. PKU is transmitted by a recessive gene, meaning that both parents must carry the gene for their child to be affected. Klinefelter's syndrome and Turner's syndrome are genetic disorders that involve sex chromosome abnormalities, while Tay-Sachs disease is a genetic disorder that involves the accumulation of a specific type of fatty substance in the brain and nervous system.
