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 was made for transcript

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.854

BS2

High AC in GnomAd4 at 11 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.103C>A (p.R35S) alteration is located in exon 2 (coding exon 1) of the DGKZ gene. This alteration results from a C to A substitution at nucleotide position 103, causing the arginine (R) at amino acid position 35 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant has not been reported in the literature in individuals affected with DGKZ-related conditions. This variant is present in population databases (rs369668814, gnomAD 0.02%). This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 35 of the DGKZ protein (p.Arg35Ser). -
