Genes affected

FCRL1 (HGNC:18509): (Fc receptor like 1) 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 contains three extracellular C2-like immunoglobulin domains, a transmembrane domain and a cytoplasmic domain with two immunoreceptor-tyrosine activation motifs. This protein may play a role in the regulation of cancer cell growth. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2009]

The c.880T>C (p.F294L) alteration is located in exon 5 (coding exon 5) of the FCRL1 gene. This alteration results from a T to C substitution at nucleotide position 880, causing the phenylalanine (F) at amino acid position 294 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
