Genes affected

MUTYH (HGNC:7527): (mutY DNA glycosylase) This gene encodes a DNA glycosylase involved in oxidative DNA damage repair. The enzyme excises adenine bases from the DNA backbone at sites where adenine is inappropriately paired with guanine, cytosine, or 8-oxo-7,8-dihydroguanine, a major oxidatively damaged DNA lesion. The protein is localized to the nucleus and mitochondria. This gene product is thought to play a role in signaling apoptosis by the introduction of single-strand breaks following oxidative damage. Mutations in this gene result in heritable predisposition to colorectal cancer, termed MUTYH-associated polyposis (MAP). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2017]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

BP6

Variant 1-45329266-TAAC-T is Benign according to our data. Variant chr1-45329266-TAAC-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 297466.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Likely_benign=2}.

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000571 (87/152242) while in subpopulation EAS AF= 0.0135 (70/5180). AF 95% confidence interval is 0.011. There are 0 homozygotes in gnomad4. There are 57 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.

BS2

High Homozygotes in GnomAdExome4 at 7 AR geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
