Variant summary

Our verdict is Pathogenic. The variant received 20 ACMG points: 20P and 0B. PVS1PS3PP5_Very_Strong

The NM_001048174.2(MUTYH):c.1143_1144dupGG(p.Glu382GlyfsTer43) variant causes a frameshift change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000694 in 1,613,984 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000712103: In vitro functional studies provide some evidence that the p.Glu410fs variant may impact protein function (Ruggieri 2013 PMID:23108399).". Synonymous variant affecting the same amino acid position (i.e. E382E) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

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 was made for transcript

Our verdict: Pathogenic. The variant received 20 ACMG points.

PVS1

Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.

PS3

PS3 evidence extracted from ClinVar submissions: SCV000712103: In vitro functional studies provide some evidence that the p.Glu410fs variant may impact protein function (Ruggieri 2013 PMID: 23108399).

PP5

Variant 1-45331514-T-TCC is Pathogenic according to our data. Variant chr1-45331514-T-TCC is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 127831.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
