Neuberg Centre For Genomic Medicine, NCGM RCV004785804 SCV005400852 uncertain significance Kleefstra syndrome 2 criteria provided, single submitter clinical testing The missense variant c.9751A>C (p.Ile3251Leu) in the KMT2C gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is reported with the allele frequency (0.002%) in the gnomAD Exomes. The amino acid Ile at position 3251 is changed to a Leu changing protein sequence and it might alter its composition and physico-chemical properties. Multiple lines of computational evidence (Polyphen - Damaging, SIFT - Damaging and MutationTaster - Disease causing) predict a damaging effect on protein structure and function for this variant. The amino acid change p.Ile3251Leu in KMT2C is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance.
