Genes affected

SIRT6 (HGNC:14934): (sirtuin 6) This gene encodes a member of the sirtuin family of NAD-dependent enzymes that are implicated in cellular stress resistance, genomic stability, aging and energy homeostasis. The encoded protein is localized to the nucleus, exhibits ADP-ribosyl transferase and histone deacetylase activities, and plays a role in DNA repair, maintenance of telomeric chromatin, inflammation, lipid and glucose metabolism. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2016]

The c.960C>G (p.C320W) alteration is located in exon 8 (coding exon 8) of the SIRT6 gene. This alteration results from a C to G substitution at nucleotide position 960, causing the cysteine (C) at amino acid position 320 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
