RCV004018304 | SCV004847468 | likely pathogenic | Neurodevelopmental disorder | 2024-03-31 | criteria provided, single submitter | clinical testing | The p.Glu182GlyfsX7 variant in KMT2E has not been previously reported in individuals with neurodevelopmental disorders nor in large population studies (gnomAD v4.0.0). This variant is predicted to cause a frameshift, which alters the protein’s amino acid sequence beginning at position 182 and leads to a premature termination codon 7 amino acids downstream. This alteration is then predicted to lead to a truncated or absent protein. Heterozygous loss of function variants in the KMT2E gene have been reported in many individuals with autosomal dominant complex neurodevelopmental disorder (O'Donnell-Luria 2019 PMID: 31079897). In summary, although additional studies are required to fully establish its clinical significance, this variant meets criteria to be classified as likely pathogenic for autosomal dominant KMTE2-related complex neurodevelopmental disorder.
