Genes affected

EXOSC1 (HGNC:17286): (exosome component 1) This gene encodes a core component of the exosome. The mammalian exosome is required for rapid degradation of AU rich element-containing RNAs but not for poly(A) shortening. The association of this protein with the exosome is mediated by protein-protein interactions with ribosomal RNA-processing protein 42 and ribosomal RNA-processing protein 46. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jan 2016]

The c.310C>T (p.R104C) alteration is located in exon 4 (coding exon 4) of the EXOSC1 gene. This alteration results from a C to T substitution at nucleotide position 310, causing the arginine (R) at amino acid position 104 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
