Genes affected

CXCR5 (HGNC:1060): (C-X-C motif chemokine receptor 5) This gene encodes a multi-pass membrane protein that belongs to the CXC chemokine receptor family. It is expressed in mature B-cells and Burkitt's lymphoma. This cytokine receptor binds to B-lymphocyte chemoattractant (BLC), and is involved in B-cell migration into B-cell follicles of spleen and Peyer patches. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Aug 2011]

CXCR5 links:

BCL9L (HGNC:23688): (BCL9 like) Enables beta-catenin binding activity. Involved in several processes, including negative regulation of transforming growth factor beta receptor signaling pathway; positive regulation of epithelial to mesenchymal transition; and positive regulation of transcription by RNA polymerase II. Located in nucleolus and nucleoplasm. Part of beta-catenin-TCF complex. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method:clinical testing

The c.247C>T (p.R83C) alteration is located in exon 2 (coding exon 2) of the CXCR5 gene. This alteration results from a C to T substitution at nucleotide position 247, causing the arginine (R) at amino acid position 83 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
