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.2011A>G (p.N671D) alteration is located in exon 14 (coding exon 13) of the SETDB2 gene. This alteration results from a A to G substitution at nucleotide position 2011, causing the asparagine (N) at amino acid position 671 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
