Genes affected
KLF6 (HGNC:2235): (KLF transcription factor 6) This gene encodes a member of the Kruppel-like family of transcription factors. The zinc finger protein is a transcriptional activator, and functions as a tumor suppressor. Multiple transcript variants encoding different isoforms have been found for this gene, some of which are implicated in carcinogenesis. [provided by RefSeq, May 2009]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

PM1
In a chain Krueppel-like factor 6 (size 282) in uniprot entity KLF6_HUMAN there are 5 pathogenic changes around while only 1 benign (83%) in NM_001300.6
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 5 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 1.8535 (below the threshold of 3.09). Trascript score misZ: 2.6969 (below the threshold of 3.09).
PP3
MetaRNN computational evidence supports a deleterious effect, 0.777

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.601C>T (p.R201W) alteration is located in exon 2 (coding exon 2) of the KLF6 gene. This alteration results from a C to T substitution at nucleotide position 601, causing the arginine (R) at amino acid position 201 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
