Criteria Specifications for this VCEP

Evidence submitted by expert panel

Phenylketonuria VCEP

PAH-specific ACMG/AMP criteria applied: PM2: 8.1e-6 allele frequency in GnomAD, not found in any other databases; PM3: [c.898G>T];[c.1199+1G>C] in a patient with mild hyperphe (180umol/L); PP4_Moderate: Single patient in Sterl 2013, BH4 defect excluded. Also identified in multiple other patients (7 publications linked through ClinVar) (PMID:22526846); PVS1: +1 canonical splice site. In summary this variant meets criteria to be classified as pathogenic for phenylketonuria in an autosomal recessive manner based on the ACMG/AMP criteria applied as specified by the PAH Expert Panel: (PM2, PM3, PP4_Moderate, PVS1).
