Genes affected

FCGR2A (HGNC:3616): (Fc gamma receptor IIa) This gene encodes one member of a family of immunoglobulin Fc receptor genes found on the surface of many immune response cells. The protein encoded by this gene is a cell surface receptor found on phagocytic cells such as macrophages and neutrophils, and is involved in the process of phagocytosis and clearing of immune complexes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2008]

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.004311353).
• BP6: Variant 1-161506415-A-G is Benign according to our data. Variant chr1-161506415-A-G is described in ClinVar as Benign. ClinVar VariationId is 402850.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.121 is higher than 0.05.
