Genes affected

BCL7A (HGNC:1004): (BAF chromatin remodeling complex subunit BCL7A) This gene is directly involved, with Myc and IgH, in a three-way gene translocation in a Burkitt lymphoma cell line. As a result of the gene translocation, the N-terminal region of the gene product is disrupted, which is thought to be related to the pathogenesis of a subset of high-grade B cell non-Hodgkin lymphoma. The N-terminal segment involved in the translocation includes the region that shares a strong sequence similarity with those of BCL7B and BCL7C. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.602G>A (p.R201Q) alteration is located in exon 5 (coding exon 5) of the BCL7A gene. This alteration results from a G to A substitution at nucleotide position 602, causing the arginine (R) at amino acid position 201 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
