Gene Symbol MLH1
Synonyms COCA2 | FCC2 | hMLH1 | HNPCC | HNPCC2 | LYNCH2 | MLH-1 | MMRCS1
Gene Description MLH1, mutL homolog 1, is a tumor suppressor (PMID: 30562755) that dimerizes with Pms2 to form a component of the DNA mismatch repair (MMR) system (PMID: 16873062), and is associated with microsatellite instability (MSI) (PMID: 30121009) and genomic stability (PMID: 31747945). MLH1 promoter hypermethylation, resulting in Mlh1 deficiency, is frequently associated with sporadic colorectal, gastric, and esophageal cancers (PMID: 23555617, PMID: 21988782, PMID: 28224663, PMID: 28454461), and germline MLH1 mutations are associated with Lynch (Hereditary Nonpolyposis Colorectal Cancer) syndrome (PMID: 15528792).

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
  • Spaces will be interpreted literally in the search. Use the percentage character '%' as a wildcard to search for multiple values
  • When searching for values delimited by '%', searches are ordered by their appearance in the text. (i.e. 'A%C' will likely return different results than 'C%A')
  • Precede text with a caret '^' to indicate search should "start with" the text
  • Follow text with a dollar sign '$' to indicate search should "end with" the preceding text

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.
