Genes affected

FCGR2B (HGNC:3618): (Fc gamma receptor IIb) The protein encoded by this gene is a low affinity receptor for the Fc region of immunoglobulin gamma complexes. The encoded protein is involved in the phagocytosis of immune complexes and in the regulation of antibody production by B-cells. Variations in this gene may increase susceptibilty to systemic lupus erythematosus (SLE). Several transcript variants encoding different isoforms have been found for this gene.

FCGR2B Gene-Disease associations (from GenCC):

• systemic lupus erythematosus

  Inheritance: Unknown Classification: SUPPORTIVE, NO_KNOWN Submitted by: Labcorp Genetics (formerly Invitae), Orphanet

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.0).
