Genes affected

GFRA3 (HGNC:4245): (GDNF family receptor alpha 3) The protein encoded by this gene is a glycosylphosphatidylinositol(GPI)-linked cell surface receptor and a member of the GDNF receptor family. It forms a signaling receptor complex with RET tyrosine kinase receptor and binds the ligand, artemin. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 28, 2022

The c.625G>C (p.E209Q) alteration is located in exon 4 (coding exon 4) of the GFRA3 gene. This alteration results from a G to C substitution at nucleotide position 625, causing the glutamic acid (E) at amino acid position 209 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
