Genes affected

DGKD (HGNC:2851): (diacylglycerol kinase delta) This gene encodes a cytoplasmic enzyme that phosphorylates diacylglycerol to produce phosphatidic acid. Diacylglycerol and phosphatidic acid are two lipids that act as second messengers in signaling cascades. Their cellular concentrations are regulated by the encoded protein, and so it is thought to play an important role in cellular signal transduction. Alternative splicing results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

The c.830C>T (p.S277L) alteration is located in exon 8 (coding exon 8) of the DGKD gene. This alteration results from a C to T substitution at nucleotide position 830, causing the serine (S) at amino acid position 277 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
