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]

The c.1133G>A (p.R378K) alteration is located in exon 8 (coding exon 8) of the GFRA3 gene. This alteration results from a G to A substitution at nucleotide position 1133, causing the arginine (R) at amino acid position 378 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
