Genes affected
UNG (HGNC:12572): (uracil DNA glycosylase) This gene encodes one of several uracil-DNA glycosylases. One important function of uracil-DNA glycosylases is to prevent mutagenesis by eliminating uracil from DNA molecules by cleaving the N-glycosylic bond and initiating the base-excision repair (BER) pathway. Uracil bases occur from cytosine deamination or misincorporation of dUMP residues. Alternative promoter usage and splicing of this gene leads to two different isoforms: the mitochondrial UNG1 and the nuclear UNG2. The UNG2 term was used as a previous symbol for the CCNO gene (GeneID 10309), which has been confused with this gene, in the literature and some databases. [provided by RefSeq, Nov 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.9).
BP6
Variant 12-109103461-G-A is Benign according to our data. Variant chr12-109103461-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 573856.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
Synonymous conserved (PhyloP=-5.38 with no splicing effect.
BS2
High AC in GnomAd4 at 9 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
