KIT (v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog, also known as CD117) encodes for the mast/stem cell growth factor receptor Kit protein. It is a receptor tyrosine kinase (RTK) expressed on a wide variety of cell types. The ligand for KIT is stem cell factor (SCF). Binding of the KIT ligand SCF to the KIT RTK activates downstream signaling pathways involved in mediating pro-growth and pro-survival signals within the cell. Mutant KIT has been implicated in the pathogenesis of several cancers including melanoma, acute leukemia, and gastrointestinal stromal tumor (GIST; PMID: 14645423; PMID: 9438854

KIT is altered in 2.60% of all cancers with gastrointestinal stromal tumor, lung adenocarcinoma, colon adenocarcinoma, conventional glioblastoma multiforme, and melanoma having the greatest prevalence of alterations [3].

KIT GENIE Cases - Top Diseases

The most common alterations in KIT are KIT Mutation (3.37%), KIT Exon 11 Mutation (1.07%), KIT Amplification (0.64%), KIT Deletion (0.54%), and KIT Exon 11 Deletion (0.52%) [3].
