Genes affected

GAD2 (HGNC:4093): (glutamate decarboxylase 2) This gene encodes one of several forms of glutamic acid decarboxylase, identified as a major autoantigen in insulin-dependent diabetes. The enzyme encoded is responsible for catalyzing the production of gamma-aminobutyric acid from L-glutamic acid. A pathogenic role for this enzyme has been identified in the human pancreas since it has been identified as an autoantibody and an autoreactive T cell target in insulin-dependent diabetes. This gene may also play a role in the stiff man syndrome. Alternative splicing results in multiple transcript variants that encode the same protein. [provided by RefSeq, Oct 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -15 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 7: AlphaMissense, Cadd, Eigen, FATHMM_MKL, MutationAssessor, phyloP100way_vertebrate, PROVEAN [when BayesDel_addAF, max_spliceai, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.009708941).

BP6

Variant 10-26219214-C-A is Benign according to our data. Variant chr10-26219214-C-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 782118.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS2

High AC in GnomAd4 at 793 AD gene.
