Genes affected
EHMT1 (HGNC:24650): (euchromatic histone lysine methyltransferase 1) The protein encoded by this gene is a histone methyltransferase that methylates the lysine-9 position of histone H3. This action marks the genomic region packaged with these methylated histones for transcriptional repression. This protein may be involved in the silencing of MYC- and E2F-responsive genes and therefore could play a role in the G0/G1 cell cycle transition. Defects in this gene are a cause of chromosome 9q subtelomeric deletion syndrome (9q-syndrome, also known as Kleefstra syndrome). Alternative splicing results in multiple transcript variants.

Likely benign, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMay 22, 2023- -
Uncertain significance, criteria provided, single submitterclinical testingNeuberg Centre For Genomic Medicine, NCGM-The missense variant c.376A>G (p.Ile126Val) in EHMT1 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 (0.001%) in the gnomad and novel in 1000 genome database. This variant has been submitted to ClinVar as a variant of Uncertain significance. The amino acid Isoleucine at position 126 is changed to a Valine changing protein sequence and it might alter its composition and physico chemical properties. The variant is predicted to be damaging by SIFT. The residue is conserved across species. For these reasons, this variant has been classified as Uncertain Significance. -
