Genes affected

EXOSC10 (HGNC:9138): (exosome component 10) Enables 3'-5'-exoribonuclease activity. Involved in several processes, including RNA catabolic process; maturation of 5.8S rRNA; and negative regulation of telomere maintenance via telomerase. Located in cytosol; nuclear lumen; and transcriptionally active chromatin. Part of nuclear exosome (RNase complex). [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.20667431).

The c.2593A>C (p.K865Q) alteration is located in exon 24 (coding exon 24) of the EXOSC10 gene. This alteration results from a A to C substitution at nucleotide position 2593, causing the lysine (K) at amino acid position 865 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
