Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM2PP5_Very_Strong
The NM_000642.3(AGL):c.1078C>T(p.His360Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.0000093 in 1,613,354 control chromosomes in the GnomAD database, with no homozygous occurrence. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. H360H) has been classified as Likely benign.

Likely pathogenic, criteria provided, single submitter | clinical testing | 3billion | Sep 01, 2022 | The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.002%). While this variant results in missense change, protein truncation variants are a common disease-causing mechanism. Same nucleotide change resulting in same amino acid change has been previously reported to be associated with AGL-related disorder (ClinVar ID: VCV000371296 / PMID: 25388549). The variant has been observed in multiple (>3) similarly affected unrelated individuals (PMID: 25388549 / 3billion dataset). The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least one similarly affected unrelated individual (PMID: 25388549 / 3billion dataset). Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline. - |

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 02, 2024 | This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 360 of the AGL protein (p.His360Tyr). This variant is present in population databases (rs763554006, gnomAD 0.006%). This missense change has been observed in individual(s) with glycogen storage disease type III (PMID: 27460348). ClinVar contains an entry for this variant (Variation ID: 371296). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt AGL protein function with a negative predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. - |
