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.

Collection Method: clinical testing

The c.2563G>A (p.V855I) alteration is located in exon 21 (coding exon 21) of the DGKQ gene. This alteration results from a G to A substitution at nucleotide position 2563, causing the valine (V) at amino acid position 855 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
