Genes affected

FCGR2C (HGNC:15626): (Fc gamma receptor IIc (gene/pseudogene)) This gene encodes one of three members of a family of low-affinity immunoglobulin gamma Fc receptors found on the surface of many immune response cells. The encoded protein is a transmembrane glycoprotein and may be involved in phagocytosis and clearing of immune complexes. An allelic polymorphism in this gene results in both coding and non-coding variants. [provided by RefSeq, Apr 2012]

The c.443T>A (p.I148N) alteration is located in exon 4 (coding exon 4) of the FCGR2C gene. This alteration results from a T to A substitution at nucleotide position 443, causing the isoleucine (I) at amino acid position 148 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
