Did you know?
WebPhenylketonuria (PKU) is a rare, autosomal recessive disease that prevents the body from breaking down one of the amino acids found in nearly all proteins: phenylalanine (Phe). The gene affected, PAH, encodes phenylalanine hydroxylase, which converts phenylalanine to tyrosine (another amino acid) in the liver. WebPhenylalanine hydroxylase deficiency and most of the cofactor defects are inherited by autosomal recessive inheritance. Affected individuals have two pathogenic variants, one inherited from each parent. Due to parents being carriers, there is a 25% recurrence risk, and in siblings who are not affected, there is a 2/3 risk for being a carrier.
