Question

How can the severity of phenylketonuria be reduced?

Answer

Phenylketonuria is a genetic disorder caused by a deficiency or reduced activity of phenylalanine hydroxylase in the liver, leading to a disorder in the metabolism of phenylalanine. These disorders are inherited in an autosomal recessive manner, with main clinical features including delayed intellectual development, neurological symptoms, eczema, skin scratching signs, pigment loss, and body odor, as well as abnormal electroencephalograms.
