Genes affected
FCER1A (HGNC:3609): (Fc epsilon receptor Ia) The immunoglobulin epsilon receptor (IgE receptor) is the initiator of the allergic response. When two or more high-affinity IgE receptors are brought together by allergen-bound IgE molecules, mediators such as histamine that are responsible for allergy symptoms are released. This receptor is comprised of an alpha subunit, a beta subunit, and two gamma subunits. The protein encoded by this gene represents the alpha subunit. [provided by RefSeq, Aug 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 12, 2023The c.566C>T (p.P189L) alteration is located in exon 6 (coding exon 4) of the FCER1A gene. This alteration results from a C to T substitution at nucleotide position 566, causing the proline (P) at amino acid position 189 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
