Genes affected
FCRLB (HGNC:26431): (Fc receptor like B) FCRL2 belongs to the Fc receptor family. Fc receptors are involved in phagocytosis, antibody-dependent cell cytotoxicity, immediate hypersensitivity, and transcytosis of immunoglobulins via their ability to bind immunoglobulin (Ig) constant regions (Chikaev et al., 2005 [PubMed 15676285]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 12, 2021The c.679A>G (p.K227E) alteration is located in exon 5 (coding exon 5) of the FCRLB gene. This alteration results from a A to G substitution at nucleotide position 679, causing the lysine (K) at amino acid position 227 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
