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]

Likely pathogenic, reviewed by expert panel | curation | ClinGen PAH Variant Curation Expert Panel | Jul 23, 2023 | The c.1357_*2delTAAAG (p.Ter453Profs) variant in PAH has been reported in multiple individuals with PAH deficiency; one with other causes of hyperphenylalninemia ruled out with panel sequencing. (PP4_Moderate; PMID: 10679941, data share with Invitae). This variant is at low frequency in population databases (TopMed AF=0.00001). This variant was detected with known pathogenic/likely pathogenic variants: p.L48 (unknown phase, PMID: 10679941); c.1066-11G>A, p.Arg408Trp, p.Arg155Pro, (unknown phase, PMID: 32668217); and Leu348Val (in trans, data share with Invitae). The deletion p.Ter453Profs is predicted to abolish the stop codon and causes an elongation of the polypeptide by 35 amino acids (PM4). In summary, this variant meets criteria to be classified as likely pathogenic for PAH. PAH-specific ACMG/AMP criteria applied: PP4_moderate, PM2-supporting, PM3_strong, PM4. - |
Likely pathogenic, criteria provided, single submitter | clinical testing | Baylor Genetics | Oct 18, 2023 | - - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 04, 2024 | This sequence change disrupts the translational stop signal of the PAH mRNA. It is expected to extend the length of the PAH protein by 33 additional amino acid residues. This variant is not present in population databases (gnomAD no frequency). This protein extension has been observed in individual(s) with PAH-related conditions (PMID: 10679941; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. For these reasons, this variant has been classified as Pathogenic. - |
