Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4_ModerateBP6BS1

The NM_000642.3(AGL):c.4214A>G(p.Glu1405Gly) variant causes a missense change. The variant allele was found at a frequency of 0.000126 in 1,613,596 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E1405K) has been classified as Uncertain significance.

Genes affected

AGL (HGNC:321): (amylo-alpha-1, 6-glucosidase, 4-alpha-glucanotransferase) This gene encodes the glycogen debrancher enzyme which is involved in glycogen degradation. This enzyme has two independent catalytic activities which occur at different sites on the protein: a 4-alpha-glucotransferase activity and a amylo-1,6-glucosidase activity. Mutations in this gene are associated with glycogen storage disease although a wide range of enzymatic and clinical variability occurs which may be due to tissue-specific alternative splicing. Alternatively spliced transcripts encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.10469803).

BP6

Variant 1-99915441-A-G is Benign according to our data. Variant chr1-99915441-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 456501.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000651 (99/152078) while in subpopulation AFR AF = 0.00236 (98/41482). AF 95% confidence interval is 0.00198. There are 0 homozygotes in GnomAd4. There are 50 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
