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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2022The c.836G>A (p.R279H) 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 836, causing the arginine (R) at amino acid position 279 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
