Genes affected

KLF5 (HGNC:6349): (KLF transcription factor 5) This gene encodes a member of the Kruppel-like factor subfamily of zinc finger proteins. The encoded protein is a transcriptional activator that binds directly to a specific recognition motif in the promoters of target genes. This protein acts downstream of multiple different signaling pathways and is regulated by post-translational modification. It may participate in both promoting and suppressing cell proliferation. Expression of this gene may be changed in a variety of different cancers and in cardiovascular disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2013]

The c.364C>A (p.Q122K) alteration is located in exon 2 (coding exon 2) of the KLF5 gene. This alteration results from a C to A substitution at nucleotide position 364, causing the glutamine (Q) at amino acid position 122 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
