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]

Nov 22, 2022

The c.374G>T (p.G125V) alteration is located in exon 6 (coding exon 4) of the FCER1A gene. This alteration results from a G to T substitution at nucleotide position 374, causing the glycine (G) at amino acid position 125 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
