Genes affected

GYS1 (HGNC:4706): (glycogen synthase 1) The protein encoded by this gene catalyzes the addition of glucose monomers to the growing glycogen molecule through the formation of alpha-1,4-glycoside linkages. Mutations in this gene are associated with muscle glycogen storage disease. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -18 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.38).

BP6

Variant 19-48970606-G-A is Benign according to our data. Variant chr19-48970606-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 725380.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000282 (43/152314) while in subpopulation SAS AF = 0.0089 (43/4834). AF 95% confidence interval is 0.00679. There are 2 homozygotes in GnomAd4. There are 36 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 2 AR gene
