Gene MLH1
Variant K618A
Impact List missense
Protein Effect unknown
Gene Variant Descriptions MLH1 K618A lies within the EXO1-interacting region and C-terminal dimerization domain of the Mlh1 protein (PMID: 22753075). The functional effect of K618A is conflicting, as it results in mismatch repair activity similar to wild-type Mlh1 in in vitro assays (PMID: 16083711, PMID: 20020535, PMID: 21120944) and stable microsatellites (PMID: 36054288), but has also been reported to have reduced binding to Pms2 (PMID: 10037723), reduced Pms2 and Mlh1 expression (PMID: 36054288), decreased mismatch repair activity in culture (PMID: 31784484), and to cause reduced cell line viability (PMID: 16982745).

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.
