Gene MLH1
Variant T82I
Impact List missense
Protein Effect loss of function
Gene Variant Descriptions MLH1 T82I lies within the ATPase domain of the Mlh1 protein (PMID: 22753075). T82I results in Mlh1 protein expression comparable to wild-type in a patient tumor sample in one study (PMID: 20587412) but reduced protein expression in culture in another study (PMID: 23403630), loss of mismatch repair activity in a yeast assay (PMID: 17510385) and in in vitro assays (PMID: 17510385, PMID: 23403630), and high microsatellite instability despite expression of Mlh1, Pms2, Msh2, and Msh6 comparable to wild-type in patient tumors (PMID: 20587412).

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.
