Genes affected

SIRT3 (HGNC:14931): (sirtuin 3) SIRT3 encodes a member of the sirtuin family of class III histone deacetylases, homologs to the yeast Sir2 protein. The encoded protein is found exclusively in mitochondria, where it can eliminate reactive oxygen species, inhibit apoptosis, and prevent the formation of cancer cells. SIRT3 has far-reaching effects on nuclear gene expression, cancer, cardiovascular disease, neuroprotection, aging, and metabolic control. [provided by RefSeq, May 2019]

Collection Method: clinical testing

The c.940C>G (p.L314V) alteration is located in exon 5 (coding exon 5) of the SIRT3 gene. This alteration results from a C to G substitution at nucleotide position 940, causing the leucine (L) at amino acid position 314 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
