Gene DNMT3A
Variant R836A
Impact List missense
Protein Effect loss of function - predicted
Gene Variant Descriptions DNMT3A R836A lies within the SAM-dependent MTase C5-type domain of the Dnmt3a protein (UniProt.org). R836A demonstrates methylation activity similar to wild-type protein in a chimeric Dnmt3a catalytic domain construct in an in vitro assay (PMID: 33826797), but results in altered substrate specificity leading to decreased CpG site methylation and increased non-CpG site methylation in in vitro assays and in cell culture (PMID: 29414941), and therefore, is predicted to lead to a loss of Dnmt3a protein function.

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.
