Genes affected

SMUG1 (HGNC:17148): (single-strand-selective monofunctional uracil-DNA glycosylase 1) This gene encodes a protein that participates in base excision repair by removing uracil from single- and double-stranded DNA. Many alternatively spliced transcript variants exist for this gene; the full-length nature is known for some but not all of the variants. [provided by RefSeq, Aug 2011]

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.002324164).
• BP6: Variant 12-54183897-C-A is Benign according to our data. Variant chr12-54183897-C-A is described in ClinVar as Benign. ClinVar VariationId is 776713.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0555 is higher than 0.05.
