Genes affected

CXCL13 (HGNC:10639): (C-X-C motif chemokine ligand 13) B lymphocyte chemoattractant, independently cloned and named Angie, is an antimicrobial peptide and CXC chemokine strongly expressed in the follicles of the spleen, lymph nodes, and Peyer's patches. It preferentially promotes the migration of B lymphocytes (compared to T cells and macrophages), apparently by stimulating calcium influx into, and chemotaxis of, cells expressing Burkitt's lymphoma receptor 1 (BLR-1). It may therefore function in the homing of B lymphocytes to follicles. [provided by RefSeq, Oct 2014]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.55C>T (p.P19S) alteration is located in exon 2 (coding exon 1) of the CXCL13 gene. This alteration results from a C to T substitution at nucleotide position 55, causing the proline (P) at amino acid position 19 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
