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]

ALKBH2 (HGNC:32487): (alkB homolog 2, alpha-ketoglutarate dependent dioxygenase) The Escherichia coli AlkB protein protects against the cytotoxicity of methylating agents by repair of the specific DNA lesions generated in single-stranded DNA. ALKBH2 and ALKBH3 (MIM 610603) are E. coli AlkB homologs that catalyze the removal of 1-methyladenine and 3-methylcytosine (Duncan et al., 2002 [PubMed 12486230]).[supplied by OMIM, Mar 2008]

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.43).

BP6

Variant 12-109098590-C-T is Benign according to our data. Variant chr12-109098590-C-T is described in ClinVar as Benign. ClinVar VariationId is 463871.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=1.14 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00581 (885/152330) while in subpopulation AFR AF = 0.0199 (829/41566). AF 95% confidence interval is 0.0188. There are 8 homozygotes in GnomAd4. There are 398 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 8 AR gene
