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.

Feb 23, 2023

The c.1778G>A (p.R593H) alteration is located in exon 14 (coding exon 14) of the EHMT2 gene. This alteration results from a G to A substitution at nucleotide position 1778, causing the arginine (R) at amino acid position 593 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
