Variant summary

Our verdict is Pathogenic. The variant received 9 ACMG points: 9P and 0B. PP3PM3PS3PP4_Moderate

This summary comes from the ClinGen Evidence Repository: PAH-specific ACMG/AMP criteria applied: PP3: Deleterious in SIFT, Polyphen2, MutationTaster; PP4_Moderate: A300S found on 56/588 hyperphenylalaninemic patients, BH4 deficiency excluded. Upgraded per ClinGen Metabolic WG. (PMID:21147011); PM3_VeryStrong: Detected with c.1066-11G>A (P), R261Q(P/LP), L48S (P), R176X (P) in 20 patients. (PMID:21147011); PS3: A300S in vitro PAH activity of 31% (PMID:17935162). 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: (PP3, PP4_Moderate, PM3_VeryStrong, PS3).

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]
