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]

This sequence change creates a premature translational stop signal (p.Lys201*) in the RTN4IP1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RTN4IP1 are known to be pathogenic (PMID: 26593267). This variant is present in population databases (rs200457692, gnomAD 0.002%). This premature translational stop signal has been observed in individual(s) with autosomal recessive early-onset optic neuropathy (PMID: 26593267). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 218933). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
