Genes affected

SETDB2 (HGNC:20263): (SET domain bifurcated histone lysine methyltransferase 2) This gene encodes a member of a family of proteins that contain a methyl-CpG-binding domain (MBD) and a SET domain and function as histone methyltransferases. This protein is recruited to heterochromatin and plays a role in the regulation of chromosome segregation. This region is commonly deleted in chronic lymphocytic leukemia. Naturally-occuring readthrough transcription occurs from this gene to the downstream PHF11 (PHD finger protein 11) gene. Alternative splicing results in multiple transcript variants.

The c.1006A>G (p.R336G) alteration is located in exon 8 (coding exon 7) of the SETDB2 gene. This alteration results from a A to G substitution at nucleotide position 1006, causing the arginine (R) at amino acid position 336 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
