Genes affected

DGKK (HGNC:32395): (diacylglycerol kinase kappa) The protein encoded by this gene is an enzyme that phosphorylates diacylglycerol, converting it to phosphatidic acid. The encoded protein is a membrane protein and is inhibited by hydrogen peroxide. Variations in this gene have been associated with hypospadias. [provided by RefSeq, Mar 2011]

The c.2883C>G (p.I961M) alteration is located in exon 21 (coding exon 21) of the DGKK gene. This alteration results from a C to G substitution at nucleotide position 2883, causing the isoleucine (I) at amino acid position 961 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
