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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2024The c.700T>C (p.Y234H) alteration is located in exon 7 (coding exon 6) of the SETDB2 gene. This alteration results from a T to C substitution at nucleotide position 700, causing the tyrosine (Y) at amino acid position 234 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
