Genes affected

SUV39H2 (HGNC:17287): (SUV39H2 histone lysine methyltransferase) Enables S-adenosyl-L-methionine binding activity; histone methyltransferase activity (H3-K9 specific); and zinc ion binding activity. Involved in chromatin assembly or disassembly and chromatin remodeling. Acts upstream of or within cellular response to hypoxia and negative regulation of transcription by RNA polymerase II. Located in chromatin. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method:clinical testing

The c.61G>C (p.D21H) alteration is located in exon 2 (coding exon 2) of the SUV39H2 gene. This alteration results from a G to C substitution at nucleotide position 61, causing the aspartic acid (D) at amino acid position 21 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
