Genes affected
FCER2 (HGNC:3612): (Fc epsilon receptor II) The protein encoded by this gene is a B-cell specific antigen, and a low-affinity receptor for IgE. It has essential roles in B cell growth and differentiation, and the regulation of IgE production. This protein also exists as a soluble secreted form, then functioning as a potent mitogenic growth factor. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.[provided by RefSeq, Jul 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2021The c.262A>G (p.I88V) alteration is located in exon 6 (coding exon 5) of the FCER2 gene. This alteration results from a A to G substitution at nucleotide position 262, causing the isoleucine (I) at amino acid position 88 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
