Question

Quizplus · Accepted Answer

Phenylketonuria (PKU) is a genetic disorder that results in the inability to metabolize phenylalanine, an essential amino acid. This leads to an excess accumulation of phenylalanine in the body, which can cause severe cognitive and developmental delays if left untreated. However, if diagnosed early, like in Wendy's case, the disorder can be managed by following a special diet low in phenylalanine, which can prevent the accumulation of harmful levels of the amino acid and reduce the risk of cognitive impairment. Hemophilia is a genetic disorder that affects blood clotting, Turner Syndrome is a genetic disorder that affects females and is caused when one of the X chromosomes is missing or incomplete, fragile X syndrome is a genetic condition that causes intellectual and developmental disabilities. None of these disorders are linked to the inability to metabolize an amino acid.
