RCV000169559 | SCV002818516 | pathogenic | Phenylketonuria | 2022-10-14 | reviewed by expert panel | curation | This c.400C>T (p.Gln134Ter) variant in PAH was detected in a patient with PKU (PMID:17096675). This variant was absent in population databases. This was predicted as a null variant in PAH where LOF is a known mechanism of disease. This is a nonsense variant in exon 4 of 13 coding exons predicted to undergo nonsense mediated decay. In summary, this variant meets criteria to be classified as pathogenic for PAH. PAH-specific ACMG/AMP criteria applied: PVS1,PM2,PP4. |

RCV000169559 | SCV000919915 | likely pathogenic | Phenylketonuria | 2018-07-27 | criteria provided, single submitter | clinical testing | Variant summary: PAH c.400C>T (p.Gln134X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory (e.g., p.Arg176X and p.Tyr206X). The variant was absent in 246228 control chromosomes (gnomAD). The variant, c.400C>T, has been reported in the literature in at least one individual affected with Phenylalanine Hydroxylase Deficiency (Phenylketonuria)(Daniele_2006). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as likely pathogenic. Based on the evidence outlined above, the variant was classified as likely pathogenic. |
