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]

The MUTYH p.Asp328= variant was not identified in the literature nor was it identified in the COGR, Cosmic, MutDB, or UMD-LSDB databases. The variant was identified in dbSNP (ID: rs587780752) as "With Likely benign, Uncertain significance allele", and in ClinVar (classified as likely benign by Invitae, Counsyl, GeneDx, Ambry Genetics and Color Genomics). The variant was identified in control databases in 4 of 277162 chromosomes at a frequency of 0.00001 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: European in 2 of 126666 chromosomes (freq: 0.00002), and South Asian in 2 of 30782 chromosomes (freq: 0.00007); it was not observed in the African, Other, Latino, Ashkenazi Jewish, East Asian, and Finnish, populations. The p.Asp328 variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. The variant occurs outside of the splicing consensus sequence and 1 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -

The c.984C>T; p.Asp328Asp variant (rs587780752, ClinVar variant ID 135993) does not alter the amino acid sequence of the MUTYH protein and computational splice site prediction algorithms do not predict a change in the nearest splice site or creation of a cryptic splice site. This variant has not been reported in medical literature or in gene specific variation databases. This variant is listed in the genome Aggregation Database (gnomAD) with an overall population frequency of 0.001% (identified on 4 out of 277,162 chromosomes). Based on the available information, the c.984C>T variant is likely to be benign. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
