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.439A>T (p.N147Y) alteration is located in exon 6 (coding exon 3) of the BCL9 gene. This alteration results from a A to T substitution at nucleotide position 439, causing the asparagine (N) at amino acid position 147 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
