Genes affected

KLF8 (HGNC:6351): (KLF transcription factor 8) This gene encodes a protein which is a member of the Sp/KLF family of transcription factors. Members of this family contain a C-terminal DNA-binding domain with three Kruppel-like zinc fingers. The encoded protein is thought to play an important role in the regulation of epithelial to mesenchymal transition, a process which occurs normally during development but also during metastasis. A pseudogene has been identified on chromosome 16. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2009]

The c.182C>T (p.A61V) alteration is located in exon 3 (coding exon 3) of the KLF8 gene. This alteration results from a C to T substitution at nucleotide position 182, causing the alanine (A) at amino acid position 61 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
