Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PVS1PP4_ModeratePM2
This summary comes from the ClinGen Evidence Repository: PAH-specific ACMG/AMP criteria applied: PM2: Absent from ExAC, gnomAD, 1000G, ESP; PVS1: Frameshift variant; PP4_Moderate: Reported in patients with PAH deficiency. Bh4 defects excluded. (PMID:9634518). 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, PVS1, PP4_Moderate).

Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Aug 12, 2021 | For these reasons, this variant has been classified as Pathogenic. This sequence change creates a premature translational stop signal (p.Ala342Hisfs*58) in the PAH gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PAH are known to be pathogenic (PMID: 1301187, 9634518). This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with phenylketonuria (PMID: 26503515, 26600521). This variant is also known as c.1023del (p.A342Hfs*59). ClinVar contains an entry for this variant (Variation ID: 102475). - |
Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Nov 15, 2023 | Variant summary: PAH c.1024delG (p.Ala342HisfsX58) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Variants downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 251246 control chromosomes. c.1024delG has been reported in the literature in individuals affected with Phenylalanine Hydroxylase Deficiency (Phenylketonuria) (e.g. Guldber_1998, Li_2015, Zhu_2013, Liu_2015). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 9634518, 26503515, 23932990, 26600521). Four submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. - |

Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Mar 28, 2017 | The c.1024delG pathogenic variant has been reported previously in association with PKU (Guldberg et al., 1998; Liu et al., 2015). The deletion causes a frameshift starting with codon Alanine 342, changes this amino acid to a Histidine residue and creates a premature Stop codon at position 58 of the new reading frame, denoted p.Ala342HisfsX58. This pathogenic variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. - |
