Abstract excerpt
The deleterious effects on the brain of phenylketonuria are caused by the saturation of the blood-brain barrier large neutral amino acid transporter type 1 (LAT1) by high plasma phenylalanine concentrations. There is only one known single nucleotide polymorphism (SNP) of the open reading frame of human LAT1, N230K. Site-directed mutagenesis of the wild type human LAT1 cDNA replicated the N230K SNP, and the...
