| Gene Variant Descriptions | KIT K558N lies within the juxtamembrane domain (exon 11) of the Kit protein (PMID: 16226710). K558N has been identified in the scientific literature (PMID: 21326036, PMID: 18294292, PMID: 34338390), but has not been biochemically characterized and therefore, its effect on Kit protein function is unknown (PubMed, Jul 2025). |
