Genes affected
FCGR3B (HGNC:3620): (Fc gamma receptor IIIb) The protein encoded by this gene is a low affinity receptor for the Fc region of gamma immunoglobulins (IgG). The encoded protein acts as a monomer and can bind either monomeric or aggregated IgG. This gene may function to capture immune complexes in the peripheral circulation. Several transcript variants encoding different isoforms have been found for this gene. A highly-similar gene encoding a related protein is also found on chromosome 1. [provided by RefSeq, Aug 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 05, 2024The c.626T>G (p.V209G) alteration is located in exon 6 (coding exon 5) of the FCGR3B gene. This alteration results from a T to G substitution at nucleotide position 626, causing the valine (V) at amino acid position 209 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
