Genes affected

DGKZ (HGNC:2857): (diacylglycerol kinase zeta) The protein encoded by this gene belongs to the eukaryotic diacylglycerol kinase family. It may attenuate protein kinase C activity by regulating diacylglycerol levels in intracellular signaling cascade and signal transduction. Alternative splicing occurs at this locus and multiple transcript variants encoding distinct isoforms have been identified. [provided by RefSeq, Nov 2010]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.098335415).

BS2

High AC in GnomAd4 at 20 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The c.182A>G (p.Q61R) alteration is located in exon 1 (coding exon 1) of the DGKZ gene. This alteration results from a A to G substitution at nucleotide position 182, causing the glutamine (Q) at amino acid position 61 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
