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.

The c.2782G>A (p.D928N) alteration is located in exon 23 (coding exon 23) of the DGKQ gene. This alteration results from a G to A substitution at nucleotide position 2782, causing the aspartic acid (D) at amino acid position 928 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
