Profile Name MSH6 loss
Gene Variant Detail

MSH6 loss (loss of function)

Relevant Treatment Approaches


  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
  • Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")


  • Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.

MSH6 loss colon carcinoma not applicable N/A Preclinical Emerging Preclinical shRNA mediated-inhibition of PTEN-induced putative kinase 1 (PINK1) in colon carcinoma cells with MSH6 loss resulted in synthetic lethality, suggesting PINK1 may be a promising therapeutic target for MSH6 deficient cancer cells (PMID: 21242281). 21242281
MSH6 loss colon cancer no benefit KU60648 Preclinical - Cell culture Actionable In a preclinical study, MSH6 deficient colon cancer cells did not respond to treatment with KU60648 in culture (PMID: 28224663). 28224663
MSH6 loss colorectal cancer predicted - sensitive unspecified immune checkpoint inhibitor Clinical Study - Cohort Actionable In a retrospective analysis, treatment with Keytruda (pembrolizumab), Opdivo (nivolumab), or the combination of Opdivo (nivolumab) and Yervoy (ipilimumab) in patients with mismatch repair-deficient colorectal cancer harboring MSH6 loss or MSH2 and MSH6 loss versus patients with PMS2 loss or MLH1 and PMS2 loss resulted in a similar objective response rate (60.0% vs. 70.6% ), but led to greater progression-free survival (PFS) rates (1-year PFS 84.2% vs. 57.8%, 2-year PFS 78.2% vs. 54.2%) (PMID: 33631043). 33631043
