Gene MLH1
Variant L550P
Impact List missense
Protein Effect unknown
Gene Variant Descriptions MLH1 L550P lies within the EXO1-interacting region and C-terminal dimerization domain of the Mlh1 protein (PMID: 22753075). The functional effect of L550P is conflicting, as it results in a loss of mismatch repair activity in an in vitro assay (PMID: 20020535) and in cell culture (PMID: 31784484), but also demonstrates mismatch repair activity, localization, and protein expression to similar levels as wild-type Mlh1 in culture (PMID: 16083711, PMID: 21120944).

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.
