The variant received 2 classification points (ACGS-UK Somatic Oncogenicity v2025). O3_Moderate

The NM_020750.3(XPO5):c.*659A>T variant causes a 3 prime UTR change involving the alteration of a non-conserved nucleotide. The gene XPO5 is a tumor suppressor gene (CancerMine: 1 TSG, 1 oncogene citations). The gene XPO5 is a known oncogene (CancerMine: 1 TSG, 1 oncogene citations). The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

XPO5 (HGNC:17675): (exportin 5) This gene encodes a member of the karyopherin family that is required for the transport of small RNAs and double-stranded RNA-binding proteins from the nucleus to the cytoplasm. The encoded protein translocates cargo through the nuclear pore complex in a RanGTP-dependent process. [provided by RefSeq, Aug 2011]

XPO5 Gene-Disease associations (from GenCC):

• nephrotic syndrome

  Inheritance: AR Classification: LIMITED Submitted by: PanelApp Australia

POLR1C (HGNC:20194): (RNA polymerase I and III subunit C) The protein encoded by this gene is a subunit of both RNA polymerase I and RNA polymerase III complexes. The encoded protein is part of the Pol core element. Mutations in this gene have been associated with Treacher Collins syndrome (TCS) and hypomyelinating leukodystrophy 11. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]
