Table 4 Types of CALR mutations in our patients. All mutations were searched for in the COSMIC or the HGMD database and are labelled with their COSMIC or HGMD identity number if it existed at the time of search. All mutations that were not found in the COSMIC and HGMD databases do not have a COSMIC or HGMD identity number and are, to our knowledge, newly identified mutations that have not yet been defined. Newly identified mutations in our patients are marked in bold. Non-frameshift mutations are underlined.
