• NM_001730.5:c.364C>A

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_001730.5(KLF5):​c.364C>A​(p.Gln122Lys) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q122P) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: KLF5 NM_001730.5 missense
• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: 3.87

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]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

Collection Method: clinical testing

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. -
