|Molecular Profile||Indication/Tumor Type||Response Type||Relevant Treatment Approaches||Therapy Name||Approval Status||Evidence Type||Efficacy Evidence||References|
|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||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|
|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|
