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

Oct 06, 2021

The c.2338G>A (p.V780M) alteration is located in exon 20 (coding exon 20) of the DGKQ gene. This alteration results from a G to A substitution at nucleotide position 2338, causing the valine (V) at amino acid position 780 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
