Impact List | deletion |
Protein Effect | gain of function - predicted |
Gene Variant Descriptions | KIT P577del results in the deletion of an amino acid in the juxtamembrane domain (exon 11) of the Kit protein at amino acid 577 (PMID: 16226710). P577del has not been characterized, however other Kit exon 11 deletions are activating (PMID: 9438854, PMID: 15365079), and therefore, is predicted to lead to a gain of Kit protein function. |
