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.130C>A (p.P44T) alteration is located in exon 1 (coding exon 1) of the BCL3 gene. This alteration results from a C to A substitution at nucleotide position 130, causing the proline (P) at amino acid position 44 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
