KLF13

Chr 15

KLF transcription factor 13

Also known as: BTEB3, FKLF2, NSLP1, RFLAT-1, RFLAT1

KLF13 encodes a zinc finger transcription factor that binds to GC-rich DNA sequences to regulate gene expression, including activation of genes in erythroid cells and repression through interaction with corepressor complexes. Mutations cause an autosomal dominant neurodevelopmental disorder with intellectual disability, developmental delay, and variable features including seizures and behavioral abnormalities. The gene has moderate tolerance to loss-of-function variants based on population genetics data.
