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]

KLF5 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.3347767).
• BS2: High AC in GnomAdExome4 at 7 AD gene.

The c.23T>G (p.M8R) alteration is located in exon 1 (coding exon 1) of the KLF5 gene. This alteration results from a T to G substitution at nucleotide position 23, causing the methionine (M) at amino acid position 8 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
