The MSH2 c.792+5A>G variant was not identified in the literature nor was it identified in the following databases: COGR, Cosmic, MutDB, UMD-LSDB, Zhejiang Colon Cancer Database, or the Mismatch Repair Genes Variant Database. The variant was identified in dbSNP (ID: rs267607935) as “With Uncertain significance allele”, ClinVar (classified as uncertain significance by InSIGHT, Counsyl, Invitae and Laboratory Corporation of America; and likely benign by Ambry Genetics and GeneDx), Clinvitae (5x), Insight Hereditary Tumors Database (1x), and in control databases in 7 of 245164 chromosomes at a frequency of 0.00003 (Genome Aggregation Database Feb 27, 2017). It was observed in the European Non-Finnish population in 7 of 111216 chromosomes (freq: 0.00006) but not in the African, Other, Latino, Ashkenazi Jewish, East Asian, European Finnish, and South Asian populations. The c.792+5A>G variant is located in the 5' splice region but does not affect the invariant +1 and +2 positions. However, positions +3 to +6 are part of the splicing consensus sequence and variants involving these positions sometimes affect splicing. In addition, 3 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing. However, this information is not predictive enough to assume pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
