Variant summary

Our verdict is Pathogenic. The variant received 6 ACMG points: 6P and 0B. PM3PM5PP4_Moderate

This summary comes from the ClinGen Evidence Repository: PAH-specific ACMG/AMP criteria applied: PM5: V245L Pathogenic; PP4_Moderate: Seen in at least 7 MHP patients. Exclusion of a defect in tetrahydrobiopterin metabolism. Upgraded per ClinGen Metabolic Workgroup. (PMID:7981714; PMID:9298832; PMID:9634518); PM3_VeryStrong: V245A detected with IVS-12nt1, R252W, L194P (both P/LP), R408W (Path). Upgraded per ClinGen SVI Workgroup (PMID:7981714; PMID:9298832; PMID:8088845). 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: (PM5, PP4_Moderate, PM3_VeryStrong).

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]
