Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_001351661.2(MACROD2):​c.540+23772G>T variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.454 in 152,106 control chromosomes in the GnomAD database, including 17,639 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.45 (17639 hom., cov: 33)
• Consequence: MACROD2 NM_001351661.2 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 1.42

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.98).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.672 is higher than 0.05.
