Web23. dec 2024 · Fenilketonuria adalah kelainan kongenital langka yang bersifat autosomal resesif. Pada pasien fenilketonuria, terjadi kelainan metabolisme fenilalanin akibat defisiensi enzim fenilalanin hidroksilase yang seharusnya mengubah fenilalanin menjadi tirosin. Kondisi ini sering juga disebut sebagai phenylalanine hydroxylase deficiency.
