Evidence submitted by expert panel

Phenylketonuria VCEP

PAH-specific ACMG/AMP criteria applied: PM2: Absent from ExAC, gnomAD, 1000G, ESP; PP3: Deleterious effect predicted in SIFT, Polyphen-2, MutationTaster. REVEL=0.929; PP4_Moderate: Detected in 1 PKU patient, primary BH4 deficiency excluded. Upgraded per ClinGen PAH EP. (PMID:23430918); PM3: Detected with c.1066-11G>A (P) (PMID:23430918). 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).

PP4_Moderate

Detected in 1 PKU patient, primary BH4 deficiency excluded. Upgraded per ClinGen PAH EP.

Detected in 1 PKU patient: previously documented Phe level >360 umol/L and a Phe level >450 umol/L at the screening visit. Patients with a diagnosis of primary BH4 deficiency were excluded from the study. PubMed:23430918

PP3

Deleterious effect predicted in SIFT, Polyphen-2, MutationTaster. REVEL=0.929

PM2

Absent from ExAC, gnomAD, 1000G, ESP

PM3

Detected with c.1066-11G>A (P)

Patient genotype: p.Y179N: c.1066-11G>A PubMed:23430918
