Genes affected

EXOSC3 (HGNC:17944): (exosome component 3) This gene encodes a non-catalytic component of the human exosome, a complex with 3'-5' exoribonuclease activity that plays a role in numerous RNA processing and degradation activities. Related pseudogenes of this gene are found on chromosome 19 and 21. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jun 2012]

Pathogenic, criteria provided, single submitter	clinical testing	Genetic Services Laboratory, University of Chicago	Dec 23, 2013	- -
Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Oct 05, 2023	This sequence change creates a premature translational stop signal (p.Glu38Asnfs*16) in the EXOSC3 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EXOSC3 are known to be pathogenic (PMID: 22544365, 23284067, 24524299). This variant is present in population databases (rs587780333, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with EXOSC3-related conditions. ClinVar contains an entry for this variant (Variation ID: 129023). For these reasons, this variant has been classified as Pathogenic. -
