Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BS2

The ENST00000305883.6(KLF11):c.1039G>T(p.Ala347Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000819 in 1,612,500 control chromosomes in the GnomAD database, with no homozygous occurrence. 14/21 in silico tools predict a benign outcome for this variant. 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. A347T) has been classified as Uncertain significance.

Genes affected

KLF11 (HGNC:11811): (KLF transcription factor 11) The protein encoded by this gene is a zinc finger transcription factor that binds to SP1-like sequences in epsilon- and gamma-globin gene promoters. This binding inhibits cell growth and causes apoptosis. Defects in this gene are a cause of maturity-onset diabetes of the young type 7 (MODY7). Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Apr 2010]

Pathogenic, no assertion criteria provided	literature only	OMIM	Mar 29, 2005	- -
Uncertain significance, criteria provided, single submitter	clinical testing	3billion	May 22, 2022	The variant is observed at an allele frequency greater than expected (0.01%) for the associated disorder in the gnomAD v2.1.1 dataset and therefore considered uncertain significant. Functional studies provide strong evidence of the variant having a damaging effect on the gene or gene product (PMID: 15774581). In silico tool predictions suggest no damaging effect of the variant on gene or gene product (REVEL: 0.18; 3Cnet: 0.00). Same nucleotide change resulting in same amino acid change has been previously reported to be associated with KLF11 related disorder (ClinVar ID: VCV000006498 / PMID: 15774581). However, the evidence of pathogenicity is insufficient at this time. Therefore, this variant is classified as uncertain significance according to the recommendation of ACMG/AMP guideline. -

This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 347 of the KLF11 protein (p.Ala347Ser). This variant is present in population databases (rs121912645, gnomAD 0.05%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with clinical features of KLF11-related conditions (PMID: 15774581, 29758564, 35108381). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 6498). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. Experimental studies have shown that this missense change affects KLF11 function (PMID: 15774581, 23589285, 31124255). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
