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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.632T>C (p.L211P) alteration is located in exon 6 (coding exon 5) of the TRMT10B gene. This alteration results from a T to C substitution at nucleotide position 632, causing the leucine (L) at amino acid position 211 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
