Gene Symbol CALR
Synonyms cC1qR | CRT | HEL-S-99n | RO | SSA
Gene Description CALR, calreticulin, is a Ca2+ binding chaperone protein that plays a role in multiple biological processes, including protein folding and quality control, calcium homeostasis, immune response, cell adhesion and migration, and cell signaling (PMID: 19940256, PMID: 28470469, PMID: 22959412). CALR frameshift mutations have been identified in myeloproliferative neoplasms, including essential thrombocytothemia and myelofibrosis (PMID: 24365789, PMID: 28470469).


  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (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 a longer phrase which contains spaces "mtor c1483f"


  • 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.

Variant Impact Protein Effect Variant Description Associated with drug Resistance
act mut unknown gain of function CALR act mut indicates that this variant results in a gain of function in the Calr protein. However, the specific amino acid change has not been identified.
mutant unknown unknown CALR mutant indicates an unspecified mutation in the CALR gene.
