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.

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 13, 2014 | The c.-18G>A alteration is located in the 5' untranslated region (5'UTR) of the MSH6 gene. This alteration consists of a G to A substitution nucleotides upstream from the first translated codon. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
