Gene DNMT3A
Variant R301W
Impact List missense
Protein Effect loss of function
Gene Variant Descriptions DNMT3A R301W lies within the PWWP domain of the Dnmt3a protein (UniProt.org). R301W results in decreased DNA binding and loss of Dnmt3a catalytic activity in in vitro assays, and a corresponding mouse variant (R297W) results in hypomethylation in cell culture (PMID: 36266353).

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.
