Genes affected

EXOSC5 (HGNC:24662): (exosome component 5) Predicted to enable RNA binding activity. Involved in DNA deamination and exonucleolytic catabolism of deadenylated mRNA. Acts upstream of or within defense response to virus. Located in nucleolus; nucleoplasm; and transcriptionally active chromatin. Part of exosome (RNase complex).

Likely pathogenic, criteria provided, single submitter	clinical testing	Mendelics	May 04, 2022	- -
Likely pathogenic, criteria provided, single submitter	curation	SIB Swiss Institute of Bioinformatics	Apr 19, 2022	This variant is interpreted as likely pathogenic for Cerebellar ataxia, brain abnormalities, and cardiac conduction defects, autosomal recessive. The following ACMG Tag(s) were applied: Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium (PM2); Cosegregation with disease in multiple affected family members in a gene definitively known to cause the disease (PP1 upgraded to moderate); For recessive disorders, detected in trans with a pathogenic variant (PM3); Multiple lines of computational evidence support a deleterious effect on the gene or gene product (PP3); Well-established functional studies show a deleterious effect (PS3 downgraded to supporting). -
