| Protein Effect | gain of function - predicted |
| Gene Variant Descriptions | FLT3 exon 14 ins refers to a series of internal tandem duplications (ITD) typically occurring in exon 14 and within the juxtamembrane domain of the Flt3 protein (PMID: 12970773). Exon 14 ins mutations often result in constitutive activation of Flt3 (PMID: 12970773) and therefore, is predicted to lead to a gain of Flt3 protein function. |
