Genes affected

BCL3 (HGNC:998): (BCL3 transcription coactivator) This gene is a proto-oncogene candidate. It is identified by its translocation into the immunoglobulin alpha-locus in some cases of B-cell leukemia. The protein encoded by this gene contains seven ankyrin repeats, which are most closely related to those found in I kappa B proteins. This protein functions as a transcriptional co-activator that activates through its association with NF-kappa B homodimers. The expression of this gene can be induced by NF-kappa B, which forms a part of the autoregulatory loop that controls the nuclear residence of p50 NF-kappa B. [provided by RefSeq, Jul 2008]

The c.193G>A (p.D65N) alteration is located in exon 1 (coding exon 1) of the BCL3 gene. This alteration results from a G to A substitution at nucleotide position 193, causing the aspartic acid (D) at amino acid position 65 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
