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]

Collection Method: clinical testing

The c.419G>A (p.R140H) alteration is located in exon 6 (coding exon 5) of the RNF170 gene. This alteration results from a G to A substitution at nucleotide position 419, causing the arginine (R) at amino acid position 140 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
