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.

Ambry Genetics

Aug 30, 2021

The c.856A>G (p.I286V) alteration is located in exon 8 (coding exon 8) of the PDK2 gene. This alteration results from a A to G substitution at nucleotide position 856, causing the isoleucine (I) at amino acid position 286 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
