Question

Quizplus · Accepted Answer

Phenylketonuria (PKU) is an autosomal recessive disorder, meaning it is caused by inheriting two copies of a mutated gene, one from each parent. It is not a chromosomal disorder and does not result in death by 5 years of age. PKU is caused by the inability to metabolize phenylalanine, leading to an accumulation of this amino acid and its byproducts in the body, which can cause brain damage and intellectual disability if left untreated. It is not caused by an accumulation of lipids in the nervous system.
