Genes affected

PPARGC1B (HGNC:30022): (PPARG coactivator 1 beta) The protein encoded by this gene stimulates the activity of several transcription factors and nuclear receptors, including estrogen receptor alpha, nuclear respiratory factor 1, and glucocorticoid receptor. The encoded protein may be involved in fat oxidation, non-oxidative glucose metabolism, and the regulation of energy expenditure. This protein is downregulated in prediabetic and type 2 diabetes mellitus patients. Certain allelic variations in this gene increase the risk of the development of obesity. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2010]

The c.62A>G (p.Y21C) alteration is located in exon 1 (coding exon 1) of the PPARGC1B gene. This alteration results from a A to G substitution at nucleotide position 62, causing the tyrosine (Y) at amino acid position 21 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
