Genes affected

PPARGC1A (HGNC:9237): (PPARG coactivator 1 alpha) The protein encoded by this gene is a transcriptional coactivator that regulates the genes involved in energy metabolism. This protein interacts with PPARgamma, which permits the interaction of this protein with multiple transcription factors. This protein can interact with, and regulate the activities of, cAMP response element binding protein (CREB) and nuclear respiratory factors (NRFs). It provides a direct link between external physiological stimuli and the regulation of mitochondrial biogenesis, and is a major factor that regulates muscle fiber type determination. This protein may be also involved in controlling blood pressure, regulating cellular cholesterol homoeostasis, and the development of obesity. [provided by RefSeq, Jul 2008]

The c.2087G>A (p.R696H) alteration is located in exon 11 (coding exon 11) of the PPARGC1A gene. This alteration results from a G to A substitution at nucleotide position 2087, causing the arginine (R) at amino acid position 696 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
