Abstract excerpt
Phenylketonuria (PKU), one of the most common inherited metabolic disorders, is caused by biallelic loss-of-function variants in the phenylalanine hydroxylase (PAH) gene. More than 1000 pathogenic variants have been described in this gene. Although genotype-phenotype correlations are imperfect, PAH genotypes can influence treatment decision-making. To better characterize the genetic landscape of PKU in Brazil, we...
