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.

Ambry Genetics

Jun 16, 2023

The c.20C>T (p.T7M) alteration is located in exon 2 (coding exon 1) of the AGK gene. This alteration results from a C to T substitution at nucleotide position 20, causing the threonine (T) at amino acid position 7 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
