| Gene Variant Descriptions | CBL Q365_E366insSK results in the insertion of two amino acids in the linker region of the Cbl protein between amino acids 365 and 366 (UniProt.org). Q365_E366insSK results in a loss of E3-ligase activity, leading to activation of FLT3, and is transforming when expressed with FLT3 or KIT (PMID: 20622007). |
