Genes affected

DGKE (HGNC:2852): (diacylglycerol kinase epsilon) Diacylglycerol kinases are thought to be involved mainly in the regeneration of phosphatidylinositol (PI) from diacylglycerol in the PI-cycle during cell signal transduction. When expressed in mammalian cells, DGK-epsilon shows specificity for arachidonyl-containing diacylglycerol. DGK-epsilon is expressed predominantly in testis. [provided by RefSeq, Jul 2008]

TRIM25 (HGNC:12932): (tripartite motif containing 25) The protein encoded by this gene is a member of the tripartite motif (TRIM) family. The TRIM motif includes three zinc-binding domains, a RING, a B-box type 1 and a B-box type 2, and a coiled-coil region. The protein is an RNA binding protein, functions as a ubiquitin E3 ligase and is involved in multiple cellular processes, including regulation of antiviral innate immunity.

ACMG classification

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 4 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 0.59049 (below the threshold of 3.09). Trascript score misZ: 0.87515 (below the threshold of 3.09). GenCC associations: The gene is linked to immunoglobulin-mediated membranoproliferative glomerulonephritis, atypical hemolytic-uremic syndrome with DGKE deficiency.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.903
