Genes affected

DGKI (HGNC:2855): (diacylglycerol kinase iota) This gene is a member of the type IV diacylglycerol kinase subfamily. Diacylglycerol kinases regulate the intracellular concentration of diacylglycerol through its phosphorylation, producing phosphatidic acid. The specific role of the enzyme encoded by this gene is undetermined, however, it may play a crucial role in the production of phosphatidic acid in the retina or in recessive forms of retinal degeneration.

The c.2747C>T (p.S916F) alteration is located in exon 28 (coding exon 28) of the DGKI gene. This alteration results from a C to T substitution at nucleotide position 2747, causing the serine (S) at amino acid position 916 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
