Genes affected

DGKQ (HGNC:2856): (diacylglycerol kinase theta) The protein encoded by this gene contains three cysteine-rich domains, a proline-rich region, and a pleckstrin homology domain with an overlapping Ras-associating domain. It is localized in the speckle domains of the nucleus, and mediates the regeneration of phosphatidylinositol (PI) from diacylglycerol in the PI-cycle during cell signal transduction.

Ambry Genetics

Apr 28, 2022

The c.2572A>G (p.M858V) alteration is located in exon 21 (coding exon 21) of the DGKQ gene. This alteration results from a A to G substitution at nucleotide position 2572, causing the methionine (M) at amino acid position 858 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
