Gene Description PMS2, PMS1 homolog 2, mismatch repair system component, interacts with MLH1 to form the MutL-alpha complex, which functions in DNA mismatch repair (PMID: 18157157, PMID: 24333356) and is associated with microsatellite instability (MSI) (PMID: 30121009) and genomic stability (PMID: 31747945). Germline PMS2 mutations are associated with Lynch syndrome (PMID: 15528792), mutations in PMS2 are associated with susceptibility to colon cancer and endometrial cancer (PMID: 24978665), and overexpression has been reported in prostate cancer (PMID: 27803051).

Filtering

  • 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")

Sorting

  • 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.
