Web1. okt 1999 · The genotypic phenotype values (GPVs) were set equal to the higher-APV allele, which was assumed to be dominant over the lower-APV allele and to determine the metabolic phenotype. GPVs for 8872 patients resulted in cut-off ranges of 0.0–2.7 for classic PKU, 2.8–6.6 for mild PKU and 6.7–10.0 for mild hyperphenylalaninaemia. WebPKU is caused by mutations in the gene that helps make an enzyme called phenylalanine hydroxylase (pronounced fen-l-AL-uh-neen hahy-DROK-suh-leys), or PAH.
