Prenatal detection of an Arg----Ter mutation at codon 111 of the PAH gene using DNA amplification.

Abstract excerpt

A CGA----TGA mutation at codon 111 in exon 3 of the phenylalanine hydroxylase (PAH) gene was recently identified in a Chinese phenylketonuria (PKU) patient. This paper reports the prenatal diagnosis of a Chinese fetus at risk for PKU using DNA amplification with PCR and oligonucleotide hybridization. RFLP analysis revealed that the fetus had inherited a PKU gene from his mother, but his paternal PAH gene was...
