Genes affected

FCMR (HGNC:14315): (Fc mu receptor) Fc receptors specifically bind to the Fc region of immunoglobulins (Igs) to mediate the unique functions of each Ig class. FAIM3 encodes an Fc receptor for IgM (see MIM 147020) (Kubagawa et al., 2009 [PubMed 19858324]; Shima et al., 2010 [PubMed 20042454]).[supplied by OMIM, Jul 2010]

The c.421T>C (p.W141R) alteration is located in exon 3 (coding exon 3) of the FCMR gene. This alteration results from a T to C substitution at nucleotide position 421, causing the tryptophan (W) at amino acid position 141 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
