Genes affected

RTN4IP1 (HGNC:18647): (reticulon 4 interacting protein 1) This gene encodes a mitochondrial protein that interacts with reticulon 4, which is a potent inhibitor of regeneration following spinal cord injury. This interaction may be important for reticulon-induced inhibition of neurite growth. Mutations in this gene can cause optic atrophy 10, with or without ataxia, cognitive disability, and seizures. There is a pseudogene for this gene on chromosome 12. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

The c.1163G>A (p.R388Q) alteration is located in exon 9 (coding exon 9) of the RTN4IP1 gene. This alteration results from a G to A substitution at nucleotide position 1163, causing the arginine (R) at amino acid position 388 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
