Genes affected

FCRL2 (HGNC:14875): (Fc receptor like 2) This gene encodes a member of the immunoglobulin receptor superfamily and is one of several Fc receptor-like glycoproteins clustered on the long arm of chromosome 1. The encoded protein has four extracellular C2-type immunoglobulin domains, a transmembrane domain and a cytoplasmic domain that contains one immunoreceptor-tyrosine activation motif and two immunoreceptor-tyrosine inhibitory motifs. This protein may be a prognostic marker for chronic lymphocytic leukemia. Alternatively spliced transcript variants have been described, but their biological validity has not been determined.

Collection Method: clinical testing

The c.1117G>A (p.G373S) alteration is located in exon 6 (coding exon 6) of the FCRL2 gene. This alteration results from a G to A substitution at nucleotide position 1117, causing the glycine (G) at amino acid position 373 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
