Genes affected

FCER1G (HGNC:3611): (Fc epsilon receptor Ig) The high affinity IgE receptor is a key molecule involved in allergic reactions. It is a tetramer composed of 1 alpha, 1 beta, and 2 gamma chains. The gamma chains are also subunits of other Fc receptors. [provided by RefSeq, Jul 2008]

Ambry Genetics

Oct 12, 2021

The c.23T>C (p.L8P) alteration is located in exon 1 (coding exon 1) of the FCER1G gene. This alteration results from a T to C substitution at nucleotide position 23, causing the leucine (L) at amino acid position 8 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
