Variant summary

Our verdict is Likely pathogenic. The variant received 8 ACMG points: 8P and 0B. PM3_StrongPP4_ModeratePM2

This summary comes from the ClinGen Evidence Repository: PAH-specific ACMG/AMP criteria applied: PM2: ExAC MAF: 0.00012; PP4_Moderate: Detected in patients with PKU/HPA. BH4 deficiency excluded. (PMID:11244681; PMID:23942198); PM3_Strong: Detected with D145V, A403V (Pathogenic) (PMID:11244681; PMID:23942198). 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, 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]
