I’ve compiled a comprehensive cross-database identifier and functional mapping reference for human KIT (KIT proto-oncogene, receptor tyrosine kinase). This document includes:
Key Statistics:
52 PDB crystal structures (highest resolution: 1.45 Å)
3,286 clinical variants in ClinVar (69 pathogenic, 37 likely pathogenic)
6,468 AlphaMissense missense pathogenicity predictions
32 FDA-approved drugs targeting KIT (including imatinib, sunitinib, avapritinib, ripretinib)
22 Reactome pathways (including 12 disease-specific pathways)
5,408+ protein interactions (STRING)
121 HPO phenotypes associated
Key Disease Associations:
Piebaldism (Definitive evidence)
Gastrointestinal stromal tumor (GIST) (Strong evidence)
Mastocytosis (Strong evidence)
Multiple myeloproliferative disorders
Notable Features:
KIT is a VIP (Very Important Pharmacogene) in PharmGKB
Key target for tyrosine kinase inhibitor therapy in GIST
Ubiquitous expression with highest levels in oocytes, skin, mammary gland, and gastrointestinal tract
Regulated by key transcription factors including MITF, GATA2, RUNX1, and SOX2
