Genes affected

DGKB (HGNC:2850): (diacylglycerol kinase beta) Diacylglycerol kinases (DGKs) are regulators of the intracellular concentration of the second messenger diacylglycerol (DAG) and thus play a key role in cellular processes. Nine mammalian isotypes have been identified, which are encoded by separate genes. Mammalian DGK isozymes contain a conserved catalytic (kinase) domain and a cysteine-rich domain (CRD). The protein encoded by this gene is a diacylglycerol kinase, beta isotype. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene.

The c.233A>G (p.D78G) alteration is located in exon 4 (coding exon 4) of the DGKB gene. This alteration results from a A to G substitution at nucleotide position 233, causing the aspartic acid (D) at amino acid position 78 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
