Genes affected

BCL6 (HGNC:1001): (BCL6 transcription repressor) The protein encoded by this gene is a zinc finger transcription factor and contains an N-terminal POZ domain. This protein acts as a sequence-specific repressor of transcription, and has been shown to modulate the transcription of STAT-dependent IL-4 responses of B cells. This protein can interact with a variety of POZ-containing proteins that function as transcription corepressors. This gene is found to be frequently translocated and hypermutated in diffuse large-cell lymphoma (DLCL), and may be involved in the pathogenesis of DLCL. Alternatively spliced transcript variants encoding different protein isoforms have been found for this gene. [provided by RefSeq, Aug 2015]

Feb 23, 2023

The c.1204C>T (p.R402C) alteration is located in exon 5 (coding exon 3) of the BCL6 gene. This alteration results from a C to T substitution at nucleotide position 1204, causing the arginine (R) at amino acid position 402 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
