Genetic Variant KLF6:p.Ser142Cys (chr10-3781892-G-C) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 5P and 2B. PM1PM2PP2BP4_Moderate

The NM_001300.6(KLF6):c.425C>G(p.Ser142Cys) variant causes a missense change. The variant allele was found at a frequency of 0.00000657 in 152,204 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S142Y) has been classified as Uncertain significance.

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: Uncertain_significance. The variant received 3 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).

BP4

Computational evidence support a benign effect (MetaRNN=0.2136155).
