Genes affected

PDK4 (HGNC:8812): (pyruvate dehydrogenase kinase 4) This gene is a member of the PDK/BCKDK protein kinase family and encodes a mitochondrial protein with a histidine kinase domain. This protein is located in the matrix of the mitrochondria and inhibits the pyruvate dehydrogenase complex by phosphorylating one of its subunits, thereby contributing to the regulation of glucose metabolism. Expression of this gene is regulated by glucocorticoids, retinoic acid and insulin. [provided by RefSeq, Jul 2008]

The c.970A>C (p.N324H) alteration is located in exon 9 (coding exon 9) of the PDK4 gene. This alteration results from a A to C substitution at nucleotide position 970, causing the asparagine (N) at amino acid position 324 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
