Genes affected
EHMT2 (HGNC:14129): (euchromatic histone lysine methyltransferase 2) This gene encodes a methyltransferase that methylates lysine residues of histone H3. Methylation of H3 at lysine 9 by this protein results in recruitment of additional epigenetic regulators and repression of transcription. This gene was initially thought to be two different genes, NG36 and G9a, adjacent to each other in the HLA locus. Alternative splicing results in multiple transcript variants.

EHMT2-AS1 (HGNC:39751): (EHMT2 and SLC44A4 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 20, 2023The c.3346G>A (p.D1116N) alteration is located in exon 27 (coding exon 27) of the EHMT2 gene. This alteration results from a G to A substitution at nucleotide position 3346, causing the aspartic acid (D) at amino acid position 1116 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
