Genes affected

MACROD2 (HGNC:16126): (mono-ADP ribosylhydrolase 2) The protein encoded by this gene is a deacetylase involved in removing ADP-ribose from mono-ADP-ribosylated proteins. The encoded protein has been shown to translocate from the nucleus to the cytoplasm upon DNA damage. [provided by RefSeq, May 2017]

The c.114C>A (p.N38K) alteration is located in exon 2 (coding exon 2) of the MACROD2 gene. This alteration results from a C to A substitution at nucleotide position 114, causing the asparagine (N) at amino acid position 38 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
