Genes affected

MSH6 (HGNC:7329): (mutS homolog 6) This gene encodes a member of the DNA mismatch repair MutS family. In E. coli, the MutS protein helps in the recognition of mismatched nucleotides prior to their repair. A highly conserved region of approximately 150 aa, called the Walker-A adenine nucleotide binding motif, exists in MutS homologs. The encoded protein heterodimerizes with MSH2 to form a mismatch recognition complex that functions as a bidirectional molecular switch that exchanges ADP and ATP as DNA mismatches are bound and dissociated. Mutations in this gene may be associated with hereditary nonpolyposis colon cancer, colorectal cancer, and endometrial cancer. Transcripts variants encoding different isoforms have been described.

MSH6 links:

FBXO11 (HGNC:13590): (F-box protein 11) This gene encodes a member of the F-box protein family which is characterized by an approximately 40 amino acid motif, the F-box. The F-box proteins constitute one of the four subunits of ubiquitin protein ligase complex called SCFs (SKP1-cullin-F-box), which function in phosphorylation-dependent ubiquitination. The F-box proteins are divided into 3 classes: Fbws containing WD-40 domains, Fbls containing leucine-rich repeats, and Fbxs containing either different protein-protein interaction modules or no recognizable motifs. The protein encoded by this gene belongs to the Fbxs class. It can function as an arginine methyltransferase that symmetrically dimethylates arginine residues, and it acts as an adaptor protein to mediate the neddylation of p53, which leads to the suppression of p53 function. This gene is known to be down-regulated in melanocytes from patients with vitiligo, a skin disorder that results in depigmentation. Polymorphisms in this gene are associated with chronic otitis media with effusion and recurrent otitis media (COME/ROM), a hearing loss disorder, and the knockout of the homologous mouse gene results in the deaf mouse mutant Jeff (Jf), a single gene model of otitis media. Alternatively spliced transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jun 2010]

The synonymous variant NM_000179.3(MSH6):c.3426G>A (p.Thr1142=) has been reported to ClinVar as Benign/Likely benign with a status of (2 stars) criteria provided, multiple submitters, no conflicts (Variation ID 237189 as of 2025-01-02). The p.Thr1142= variant is not predicted to disrupt the existing donor splice site 13bp upstream by any splice site algorithm. The p.Thr1142= variant results in a substitution of a base that is not predicted conserved by GERP++ and PhyloP. For these reasons, this variant has been classified as Likely Benign -

MSH6, EXON5, c.3426G>A, p.Thr1142=, Heterozygous, Likely BenignrnThe MSH6 p.Thr1142= variant was not identified in the literature nor was it identified in the UMD-LSDB database. The variant was identified in dbSNP (ID: rs747771350) as â€šÃ„ÃºWith Uncertain significance alleleâ€šÃ„Ã¹ and ClinVar (classified as likely benign by Invitae, Ambry Genetics and 3 other submitters; and as uncertain significance by Integrated Genetics/Laboratory Corporation of America). The variant was identified in control databases in 5 of 277126 chromosomes at a frequency of 0.00002 (Genome Aggregation Database Feb 27, 2017). It was observed in the following populations: Other in 2 of 6464 chromosomes (freq: 0.0003), European Non-Finnish in 1 of 126640 chromosomes (freq: 0.000008), East Asian in 1 of 18870 chromosomes (freq: 0.00005), and South Asian in 1 of 30778 chromosomes (freq: 0.00003); it was not observed in the African, Latino, Ashkenazi Jewish, or European Finnish populations. The variant was identified by our laboratory in a patient with pancreatic cancer, as co-occurring with a pathogenic MSH6 variant (c.3940C>T, p.Gln1314*), increasing the likelihood the variant does not have clinical significance. The p.Thr1142= 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. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. 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.rnAssessment Date: 2019/07/15 -
