Genes affected

EXOSC8 (HGNC:17035): (exosome component 8) This gene encodes a 3'-5' exoribonuclease that specifically interacts with mRNAs containing AU-rich elements. The encoded protein is part of the exosome complex that is important for the degradation of numerous RNA species. A pseudogene of this gene is found on chromosome 6. [provided by RefSeq, Mar 2009]

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 10 of the EXOSC8 protein (p.Pro10Ser). This variant is present in population databases (rs764347456, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with EXOSC8-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
