Genes affected

PDK1 (HGNC:8809): (pyruvate dehydrogenase kinase 1) Pyruvate dehydrogenase (PDH) is a mitochondrial multienzyme complex that catalyzes the oxidative decarboxylation of pyruvate and is one of the major enzymes responsible for the regulation of homeostasis of carbohydrate fuels in mammals. The enzymatic activity is regulated by a phosphorylation/dephosphorylation cycle. Phosphorylation of PDH by a specific pyruvate dehydrogenase kinase (PDK) results in inactivation. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jun 2013]

The c.821A>G (p.Y274C) alteration is located in exon 7 (coding exon 7) of the PDK1 gene. This alteration results from a A to G substitution at nucleotide position 821, causing the tyrosine (Y) at amino acid position 274 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
