KLF6

Chr 10

KLF transcription factor 6

Also known as: BCD1, CBA1, COPEB, CPBP, GBF, PAC1, ST12, ZF9

KLF6 encodes a zinc finger transcription factor that activates gene transcription by binding GC box motifs and may function in B-cell growth and development. Mutations cause gastric cancer and prostate cancer as somatic (acquired) alterations rather than inherited germline conditions. This gene is highly constrained against loss-of-function variants (pLI 0.98, LOEUF 0.25), indicating it is essential for normal cellular function.

Clinical SummaryKLF6
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 0.98). One damaged copy is likely sufficient to cause disease.
