Criteria Specification Information

Criteria Specifications for this VCEP
Evidence submitted by expert panel
Phenylketonuria VCEP
PAH-specific ACMG/AMP criteria applied: PVS1: Nonsense variant; PP4_Moderate: Seen in multiple Chinese PKU patients. BH4 deficiency excluded. (PMID:1301187; PMID:2816939; PMID:9860305); PM3_very-strong: Detected in trans with 6 known pathogenic variants: p.R158Q; p.R241C; p.R243Q; p.E280K; p.Y356*; p.R413P (PMID:15503242, 26322415). 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: (PVS1, PP4_Moderate, PM3_very-strong).
