Genes affected

AGK (HGNC:21869): (acylglycerol kinase) The protein encoded by this gene is a mitochondrial membrane protein involved in lipid and glycerolipid metabolism. The encoded protein is a lipid kinase that catalyzes the formation of phosphatidic and lysophosphatidic acids. Defects in this gene have been associated with mitochondrial DNA depletion syndrome 10.

This sequence change creates a premature translational stop signal (p.Arg9*) in the AGK gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in AGK are known to be pathogenic (PMID: 22284826). This variant is present in population databases (rs139967538, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with AGK-related conditions. For these reasons, this variant has been classified as Pathogenic. -
