Genes affected
EXOSC9 (HGNC:9137): (exosome component 9) This gene encodes a component of the human exosome, a exoribonuclease complex which processes and degrades RNA in the nucleus and cytoplasm. This component may play a role in mRNA degradation and the polymyositis/scleroderma autoantigen complex. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2011]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 06, 2023This sequence change creates a premature translational stop signal (p.Tyr43*) in the EXOSC9 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EXOSC9 are known to be pathogenic (PMID: 29727687, 33040083). This variant is present in population databases (rs772936359, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with EXOSC9-related conditions. ClinVar contains an entry for this variant (Variation ID: 1964976). For these reasons, this variant has been classified as Pathogenic. -
