Genes affected

RTN4R (HGNC:18601): (reticulon 4 receptor) This gene encodes the receptor for reticulon 4, oligodendrocyte myelin glycoprotein and myelin-associated glycoprotein. This receptor mediates axonal growth inhibition and may play a role in regulating axonal regeneration and plasticity in the adult central nervous system. [provided by RefSeq, Jul 2008]

Ambry Genetics

Oct 10, 2023

The c.1393G>A (p.V465M) alteration is located in exon 2 (coding exon 2) of the RTN4R gene. This alteration results from a G to A substitution at nucleotide position 1393, causing the valine (V) at amino acid position 465 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
