Genes affected

RTN4 (HGNC:14085): (reticulon 4) This gene belongs to the family of reticulon encoding genes. Reticulons are associated with the endoplasmic reticulum, and are involved in neuroendocrine secretion or in membrane trafficking in neuroendocrine cells. The product of this gene is a potent neurite outgrowth inhibitor which may also help block the regeneration of the central nervous system in higher vertebrates. Alternatively spliced transcript variants derived both from differential splicing and differential promoter usage and encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

The c.3565C>T (p.R1189C) alteration is located in exon 9 (coding exon 9) of the RTN4 gene. This alteration results from a C to T substitution at nucleotide position 3565, causing the arginine (R) at amino acid position 1189 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
