Genes affected
MSH2 (HGNC:7325): (mutS homolog 2) This locus is frequently mutated in hereditary nonpolyposis colon cancer (HNPCC). When cloned, it was discovered to be a human homolog of the E. coli mismatch repair gene mutS, consistent with the characteristic alterations in microsatellite sequences (RER+ phenotype) found in HNPCC. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 31, 2018 | The c.-102T>A variant is located in the 5' untranslated region (5’ UTR) of the MSH2 gene. This variant results from a T to A substitution 102 bases upstream from the first translated codon. This nucleotide position is not well conserved in available vertebrate species, and adenine is the reference nucleotide in many species. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
