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.

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.07328605 fraction of the gene. Cryptic splice site detected, with MaxEntScore 8.7, offset of 35, new splice context is: aagGTgaga. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 7-141611288-G-T is Pathogenic according to our data. Variant chr7-141611288-G-T is described in ClinVar as Pathogenic. ClinVar VariationId is 521660.Status of the report is criteria_provided_single_submitter, 1 stars.
