NM_000152.5:c.379_380del (p.Cys127LeufsTer18) variant in GAA is a frameshift variant predicted to cause a premature stop codon in biologically-relevant-exon 2/20, leading to nonsense mediated decay in a gene in which loss-of-function is an established disease mechanism (PVS1). At least 4 patients with Pompe disease and this variant have been reported that meet the ClinGen LSD VCEP’s specifications for PP4_Moderate. Of these patients, the available data includes documentation of laboratory values showing GAA deficiency (PMIDs 18757064, 24245577, 24715333, 30049495, 33162552). Furthermore, one of these patients had documented features consistent with infantile onset Pompe disease (PMID 24715333, 33162552) and another was on enzyme replacement therapy (PMID 30049495)(PP4_Moderate). These patients are all compound heterozygous for the variant and another pathogenic variant in GAA, phase unknown, including c.525delT (PMID 24715333, 33162552), “del exon 18” (PMID 9660056), and c.-32-13T>G (PMID 17573812, 17643989, 18757064, 24245577, 33458579; at least two patients). Total 2 points (PM3_Strong). Another patients is compound heterozygous for the variant and c.2104C>T (p.Arg702Cys); phase unconfirmed (PMID 30049495). The in trans data from this patient will be used in the assessment of p.Arg702Cys and was not included here in order to avoid circular logic. The variant is absent in gnomAD v2.1.1 (PM2_Supporting). There is a ClinVar entry for this variant (Variation ID: 552747, two star review status) with two submitters classifying the variant as pathogenic. In summary, this variant meets the criteria to be classified as pathogenic for Pompe disease. GAA-specific ACMG/AMP criteria met, as specified by the ClinGen LSD VCEP Specification Version 2.0): PVS1, PM3_Strong, PP4_Moderate, PM2_Supporting. (less)

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 552747). This premature translational stop signal has been observed in individual(s) with Pompe disease (PMID: 9660056). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Cys127Leufs*18) in the GAA gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GAA are known to be pathogenic (PMID: 18425781, 22252923). (less)

HelpRecord last updated Mar 17, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
