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]

The c.121A>G (p.T41A) alteration is located in exon 2 (coding exon 2) of the EXOSC9 gene. This alteration results from a A to G substitution at nucleotide position 121, causing the threonine (T) at amino acid position 41 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
