Question

Quizplus · Accepted Answer

Phenylketonuria (PKU) is an inherited disorder caused by a mutation in the gene responsible for making the enzyme phenylalanine hydroxylase. It follows an autosomal recessive inheritance pattern, meaning that an individual needs to inherit the mutated gene from both parents to develop the disorder. PKU is not a chromosomal disorder, nor does it cause death by 5 years of age. Additionally, it is not caused by an accumulation of lipids in the nervous system, but rather by an inability to metabolize the amino acid phenylalanine properly.
