ClinGen PAH Variant Curation Expert Panel RCV003479002 SCV004222622 pathogenic Phenylketonuria 2023-12-30 reviewed by expert panel curation The c.466G>C (p.Ala156Pro) variant in PAH has been reported in multiple individuals with PAH deficiency (BH4 deficiency excluded). (PMID: 26322415). This variant is absent in population databases. This variant was detected in trans with multiple pathogenic variants: p.H220P (PMID 26322415); c.611A>G (aka EX6-96A>G, PMID: 26600521); p.V5Sfs*33, p.R158W, p.R241C (2 patients), p.R261Q, p.R400T, p.T418P (PMID: 30050108). Functional studies show the PAH A156P mutant produces reduced protein (8.7% of wild type), with a residual enzyme activity of 10.4% (PMID 24327145). Computational evidence is conflicting. In summary, this variant meets criteria to be classified as pathogenic for PAH. PAH-specific ACMG/AMP criteria applied: PM3_very-strong, PM2_supporting, PP4_Moderate, PS3_supporting.
