| Variant | E562_L576del |
| Impact List | deletion |
| Protein Effect | gain of function - predicted |
| Gene Variant Descriptions | KIT E562_L576del results in the deletion of 15 amino acids in the juxtamembrane domain (exon 11) of the Kit protein from amino acids 562 to 576 (PMID: 16226710). E562_L576del has not been characterized, however similar Kit exon 11 deletions are activating (PMID: 9438854, PMID: 15365079), and therefore, is predicted to lead to a gain of Kit protein function. |
