• rs148586321
• NM_002611.5:c.872G>T

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_002611.5(PDK2):​c.872G>T​(p.Arg291Leu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R291Q) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 31)
• Consequence: PDK2 NM_002611.5 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 4.01
• Publications: 0 publications found

Genes affected

PDK2 (HGNC:8810): (pyruvate dehydrogenase kinase 2) This gene encodes a member of the pyruvate dehydrogenase kinase family. The encoded protein phosphorylates pyruvate dehydrogenase, down-regulating the activity of the mitochondrial pyruvate dehydrogenase complex. Overexpression of this gene may play a role in both cancer and diabetes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
