Genes affected

AMFR (HGNC:463): (autocrine motility factor receptor) This locus encodes a glycosylated transmembrane receptor. Its ligand, autocrine motility factor, is a tumor motility-stimulating protein secreted by tumor cells. The encoded receptor is also a member of the E3 ubiquitin ligase family of proteins. It catalyzes ubiquitination and endoplasmic reticulum-associated degradation of specific proteins. [provided by RefSeq, Feb 2012]

The c.1345A>G (p.I449V) alteration is located in exon 10 (coding exon 10) of the AMFR gene. This alteration results from a A to G substitution at nucleotide position 1345, causing the isoleucine (I) at amino acid position 449 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
