Genes affected

GLUD2 (HGNC:4336): (glutamate dehydrogenase 2) The protein encoded by this gene is localized to the mitochondrion and acts as a homohexamer to recycle glutamate during neurotransmission. The encoded enzyme catalyzes the reversible oxidative deamination of glutamate to alpha-ketoglutarate. This gene is intronless.[provided by RefSeq, Jan 2010]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 5 ACMG points.

PVS1

Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.754 CDS is truncated, and there are 1 pathogenic variants in the truncated region.

PP5

Variant X-121048096-C-T is Pathogenic according to our data. Variant chrX-121048096-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 2690949.Status of the report is criteria_provided_single_submitter, 1 stars.

BS2

High Hemizygotes in GnomAd4 at 6 geneVariant has number of hemizygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
