Genes affected

BCL9 (HGNC:1008): (BCL9 transcription coactivator) BCL9 is associated with B-cell acute lymphoblastic leukemia. It may be a target of translocation in B-cell malignancies with abnormalities of 1q21. Its function is unknown. The overexpression of BCL9 may be of pathogenic significance in B-cell malignancies. [provided by RefSeq, Jul 2008]

Dec 16, 2023

The c.767C>T (p.P256L) alteration is located in exon 8 (coding exon 5) of the BCL9 gene. This alteration results from a C to T substitution at nucleotide position 767, causing the proline (P) at amino acid position 256 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
