| Protein Effect | loss of function |
| Gene Variant Descriptions | KIT E839K lies within the tyrosine kinase domain 2 of the Kit protein (PMID: 17555444). E839K results in impaired Kit protein maturation, a loss of Kit phosphorylation, and dominant inhibition of activating Kit mutations in cultured cells (PMID: 9990072, PMID: 15790786). |
