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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2024The c.439A>G (p.M147V) alteration is located in exon 3 (coding exon 3) of the GFRA3 gene. This alteration results from a A to G substitution at nucleotide position 439, causing the methionine (M) at amino acid position 147 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
