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 GeneticsNov 09, 2022The c.206G>A (p.S69N) alteration is located in exon 5 (coding exon 3) of the FCER1A gene. This alteration results from a G to A substitution at nucleotide position 206, causing the serine (S) at amino acid position 69 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
