Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PP3PM5PM3_StrongPP4_ModeratePM2

This summary comes from the ClinGen Evidence Repository: PAH-specific ACMG/AMP criteria applied: PM2: Extremely low frequency in ExAC, gnomAD, 1000G, ESP (0.000077- 0.0001518); PP3: Predicted deleterious in SIFT, PolyPhen2, MutationTaster; PM5: R241C (VarID 102803) is Pathogenic in ClinVar based on 3 submitters; PP4_Moderate: R241H seen in 1 PKU patient. BH4 deficiency ruled out. Upgraded per ClinGen Metabolism WG. (PMID:8268925); PM3_Strong: R241H detected in trans with pathogenic variants (IVS10, R408W, R252W). Upgraded per ClinGen SVI Workgroup. (PMID:9429153). 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, PP3, PM5, PP4_Moderate, PM3_Strong).

Genes affected
PAH (HGNC:8582): (phenylalanine hydroxylase) This gene encodes a member of the biopterin-dependent aromatic amino acid hydroxylase protein family. The encoded phenylalanine hydroxylase enzyme hydroxylates phenylalanine to tyrosine and is the rate-limiting step in phenylalanine catabolism. Deficiency of this enzyme activity results in the autosomal recessive disorder phenylketonuria. [provided by RefSeq, Aug 2017]
