KLF6

Overview

KLF6 (Kruppel-Like Factor 6) is a zinc-finger transcription factor with tumor-suppressive activity implicated in a number of solid tumors. It regulates genes involved in cell growth, differentiation, and apoptosis. In cancer genomics, KLF6 is recurrently mutated in a subset of renal cell carcinomas and other solid tumors, though it is not among the most frequently altered drivers in any single tumor type.

Alterations observed in the corpus

  • Mutated in ~5% of unclassified renal cell carcinoma (uRCC, n=62 MSKCC cohort) alongside other recurrent mutations such as ATRX (7%), DNMT3A (5%), SMARCB1 (5%), NOTCH2 (5%), TP53 (5%), PBRM1 (3%), CHEK2 (3%), and BRCA2; classified as an additional recurrent mutation outside the four main uRCC molecular subsets. PMID:27713405

Cancer types (linked)

  • URCC: Observed in ~5% of high-grade unclassified RCC in an MSKCC cohort (n=62); mutations cluster outside the four major molecular subsets (NF2-loss, mTORC1-hyperactive, FH-deficient, ALK-translocation). PMID:27713405

Co-occurrence and mutual exclusivity

  • No specific co-occurrence or mutual exclusivity patterns reported for KLF6 in the corpus.

Therapeutic relevance

  • No direct therapeutic implication reported for KLF6 in the corpus. The uRCC study identifies subset-specific therapy targets (e.g., mTOR inhibitors for mTORC1-hyperactive, YAP inhibitors for NF2-loss) but KLF6-mutated cases fall outside these defined subsets. PMID:27713405

Open questions

  • Whether KLF6 mutations in uRCC are drivers or passengers remains unresolved; functional validation is not presented in the citing study.
