RCV000675156 | SCV000852116 | likely pathogenic | Phenylketonuria | 2018-08-10 | reviewed by expert panel | curation | PAH-specific ACMG/AMP criteria applied: PM2: absent from ExAC, gnomAD, 1000G, ESP. PAGE MAF=0.00066; PP3: Deleterious effect predicted in SIFT, Polyphen-2, MutationTaster. REVEL=0.967; PP4_Moderate: Detected in a patient with classic PKU. Cofactor deficiency excluded. (PMID:10679941); PM3: Detected in trans with R408W (P) (PMID:10679941). In summary this variant meets criteria to be classified as likely pathogenic for phenylketonuria in an autosomal recessive manner based on the ACMG/AMP criteria applied as specified by the PAH Expert Panel: (PM2, PP3, PP4_Moderate, PM3). |

RCV000675156 | SCV003441289 | pathogenic | Phenylketonuria | 2024-03-10 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 155 of the PAH protein (p.Arg155Pro). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with hyperphenylalaninemia (PMID: 10679941, 26666653). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 102687). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt PAH protein function with a positive predictive value of 80%. This variant disrupts the p.Arg155 amino acid residue in PAH. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 23514811). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. |
