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]

EXOSC9 links:

CCNA2 (HGNC:1578): (cyclin A2) The protein encoded by this gene belongs to the highly conserved cyclin family, whose members function as regulators of the cell cycle. This protein binds and activates cyclin-dependent kinase 2 and thus promotes transition through G1/S and G2/M. [provided by RefSeq, Aug 2016]

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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals affected with EXOSC9-related conditions. This variant is present in population databases (rs745543259, ExAC 0.009%). This variant, c.1355_1357del, results in the deletion of 1 amino acid(s) of the EXOSC9 protein (p.Lys452del), but otherwise preserves the integrity of the reading frame. -
