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]

Collection Method: clinical testing

The c.467C>A (p.P156H) alteration is located in exon 6 (coding exon 3) of the BCL9 gene. This alteration results from a C to A substitution at nucleotide position 467, causing the proline (P) at amino acid position 156 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
