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]

DGKE links:

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.

This sequence change creates a premature translational stop signal (p.Trp322*) in the DGKE gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DGKE are known to be pathogenic (PMID: 23274426, 23542698). This variant is present in population databases (rs138924661, gnomAD 0.02%). This premature translational stop signal has been observed in individuals with nephrotic syndrome and atypical hemolytic uremic syndrome (PMID: 23542698, 25135762, 25854283, 28496993). ClinVar contains an entry for this variant (Variation ID: 135641). For these reasons, this variant has been classified as Pathogenic. -
