| Gene Variant Descriptions | KIT E554K lies within the juxtamembrane domain (exon 11) of the Kit protein (PMID: 16226710). E554K has been identified in sequencing studies (PMID: 21642685, PMID: 36948401, PMID: 37774052), but has not been biochemically characterized and therefore, its effect on Kit protein function is unknown (PubMed, Sep 2025). |
