Autosomal recessive mutations in the 6-pyruvoyltetrahydropterin synthase (PTPS) gene are the most common reason for hyperphenylalaninemia due to tetrahydrobiopterin deficiency. We used the previously isolated PTPS cDNA as a probe and identified the human gene, PTS, located on chromosome 11q22.3-q23.3, and a retropseudogene, PTS-P1, assigned to 9p12-p13 (symbols approved by the human genome nomenclature committee). PTS-P1 has 74% similarity to the 3' portion of PTPS cDNA. The PTS gene spans about 8 kb and consists of 6 exons, as revealed by DNA-sequence analysis. This gene structure differs from that published previously which was reported to contain only two exons [Ashida, A., Owada, M. & Hatakeyama, K. (1994) Genomics 24,408-410]. By means of intron-specific primers, we amplified exon 3 from genomic DNA of a PTPS-deficient patient and found a mutation in the 3' acceptor splice site, which is responsible for skipping of exon 3.
