ClinGen PAH Variant Curation Expert Panel RCV001789754 SCV002032191 likely pathogenic Phenylketonuria 2020-08-17 reviewed by expert panel curation The c.1159T>C (p.Tyr387His) variant in PAH has been reported in multiple individuals with PAH deficiency (BH4 deficiency excluded, PMID: 21147011, 21890392). This variant is absent in population databases. This variant was detected with multiple pathogenic variants: p.L48S, p.Y204X (PMID: 21147011); p.T323del (PMID: 9169088); c.754C>T, p.Arg252Trp (PMID: 21890392); p.Ala395Pro (PMID: 23357515); p.R261Q, c.782G>A (PMID: 23690520). Computational evidence support a deleterious effect. In summary, this variant meets criteria to be classified as likely pathogenic for PAH. PAH-specific ACMG/AMP criteria applied: PP4_Moderate, PM2, PM3_strong, PP3.
Invitae RCV001789754 SCV003441281 pathogenic Phenylketonuria 2024-01-10 criteria provided, single submitter clinical testing This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 387 of the PAH protein (p.Tyr387His). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with hyperphenylalaninemia (PMID: 23357515, 23856132, 32668217). ClinVar contains an entry for this variant (Variation ID: 102539). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on PAH protein function. For these reasons, this variant has been classified as Pathogenic.
