Illegitimate transcription of phenylalanine hydroxylase for detection of mutations in patients with phenylketonuria.
Illegitimately transcribed phenylalanine hydroxylase mRNA was amplified using the polymerase chain reaction from both fibroblasts and Epstein-Barr virus-transformed lymphocytes. This method was used to study mutations of this gene in patients with phenylketonuria and known point mutations were easily detected. Illegitimate transcription was successful for studying splicing defects and it was found that the previously described mutation which changes G to A at the 5' donor site of intron 7 causes exon 7 to be spliced out.
