Genes affected

RNF170 (HGNC:25358): (ring finger protein 170) This gene encodes a RING domain-containing protein that resides in the endoplasmic reticulum (ER) membrane. This protein functions as an E3 ubiquitin ligase and mediates ubiquitination and processing of inositol 1,4,5-trisphosphate (IP3) receptors via the ER-associated protein degradation pathway. It is recruited to the activated IP3 receptors by the ERLIN1/ERLIN2 complex to which it is constitutively bound. Mutations in this gene are associated with autosomal dominant sensory ataxia. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jun 2012]

The missense c.493G>C (p.Gly165Arg) variant in RNF170 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.Gly165Arg variant is novel (not in any individuals) in gnomAD Exomes and 1000 Genomes. This variant has not been reported to the ClinVar database. The amino acid change p.Gly165Arg in RNF170 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Gly at position 165 is changed to a Arg changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as Variant of Uncertain Significance (VUS). -
