Genes affected

SIRT4 (HGNC:14932): (sirtuin 4) This gene encodes a member of the sirtuin family of proteins, homologs to the yeast Sir2 protein. Members of the sirtuin family are characterized by a sirtuin core domain and grouped into four classes. The functions of human sirtuins have not yet been determined; however, yeast sirtuin proteins are known to regulate epigenetic gene silencing and suppress recombination of rDNA. Studies suggest that the human sirtuins may function as intracellular regulatory proteins with mono-ADP-ribosyltransferase activity. The protein encoded by this gene is included in class IV of the sirtuin family. [provided by RefSeq, Jul 2008]

The c.760G>A (p.D254N) alteration is located in exon 3 (coding exon 2) of the SIRT4 gene. This alteration results from a G to A substitution at nucleotide position 760, causing the aspartic acid (D) at amino acid position 254 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
