What is the official name of the MSH6 gene?
The official name of this gene is “mutS homolog 6.”
MSH6 is the gene's official symbol. The MSH6 gene is also known by other names, listed below.

What is the normal function of the MSH6 gene?
The MSH6 gene provides instructions for making a protein that plays an essential role in repairing DNA. This protein helps fix mistakes that are made when DNA is copied (DNA replication) in preparation for cell division. The MSH6 protein joins with another protein called MSH2 (produced from the MSH2 gene) to form a protein complex. This complex identifies locations on the DNA where mistakes have been made during DNA replication. Another group of proteins, the MLH1-PMS2 protein complex, then repairs the errors. The MSH6 gene is a member of a set of genes known as the mismatch repair (MMR) genes.
How are changes in the MSH6 gene related to health conditions?
Genetics Home Reference provides information about ovarian cancer, which is also associated with changes in the MSH6 gene.
Where is the MSH6 gene located?
Cytogenetic Location: 2p16
Molecular Location on chromosome 2: base pairs 47,783,082 to 47,806,953
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The MSH6 gene is located on the short (p) arm of chromosome 2 at position 16.
More precisely, the MSH6 gene is located from base pair 47,783,082 to base pair 47,806,953 on chromosome 2.
