GeneDx RCV000089000 SCV000239043 pathogenic not provided 2017-08-29 criteria provided, single submitter clinical testing The c.60+5 G>T variant in the PAH gene has been reported as a pathogenic variant in the PAH Consortium database. Patients who are homozygous for c.60+5 G>T or who are compound heterozygous for c.60+5 G>T and a severe PAH mutation are reported as having classic phenylketonuria (PKU) (BIOPKU Database). The responsiveness of the c.60+5 G>T variant to tetrahydrobiopterin therapy is not clear (Zurfluh et al., 2008).
Invitae RCV000173096 SCV000629202 pathogenic Phenylketonuria 2018-12-19 criteria provided, single submitter clinical testing This sequence change falls in intron 1 of the PAH gene. It does not directly change the encoded amino acid sequence of the PAH protein. This variant is present in population databases (rs62514895, ExAC 0.02%). This variant has been reported as homozygous or co-occuring with a second PAH variant in multiple individuals affected with PKU or HPA (PMID: 24941924, 24368688, Invitae). It has been observed as a prevalent PAH mutation in a small group of individuals in Mexico including one homozygous individual affected with classic PKU (PMID: 24941924).  ClinVar contains an entry for this variant (Variation ID: 102751). Nucleotide substitutions within the consensus splice site are relatively common causes of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of nucleotide changes on RNA splicing suggest that this variant may alter RNA splicing. For these reasons, this variant has been classified as Pathogenic.
