Abstract

Pathogenic variants in EXOSC3, a noncatalytic subunit of the RNA exosome, cause pontocerebellar hypoplasia type 1B (PCH1B), yet substantial variability in disease severity is observed among individuals carrying different EXOSC3 alleles. The molecular mechanisms of RNA exosome dysfunction in individuals carrying EXOSC3 p.G191 variants remains unresolved. To address this, we generated CRISPR/Cas9-engineered human cell models harboring EXOSC3 p.G191 variants and performed integrated transcriptomic, proteomic, and computational structural analyses. EXOSC3 p.G191 variants produced extensive, allele- and dosage-dependent alterations in gene expression and splicing, with heterozygous variants causing broad but attenuated disruption relative to homozygous EXOSC3 G191D/G191D cells. All EXOSC3 G191 variants promoted increased skipping of exon 3 in EXOSC3 transcripts, generating a short isoform predicted to encode an unstable proteoform. Molecular dynamics and λ-dynamics simulations predicted substantial thermodynamic destabilization of all EXOSC3 G191 variant proteoforms, consistent with reduced protein abundance and thermal stability measured by global proteomics and PISA. At the protein complex level, EXOSC3 p.G191 variants were associated with coordinated decreases in all RNA exosome core subunits and the exonuclease EXOSC10, consistent with destabilization of RNA exosome assembly and orphan protein decay. In contrast, the catalytic exonuclease DIS3 and multiple independent RNA processing pathways were upregulated, indicating compensatory recalibration of RNA metabolism. Together, these findings link variant-induced alternative splicing, RNA exosome complex destabilization, and adaptive network responses to phenotypic variability in EXOSC3 p.G191-associated disease.

TL;DR

CRISPR/Cas9-engineered HEK293T cells carrying EXOSC3 p.G191 variants show allele- and dosage-dependent transcriptome, splicing, proteome, and protein-stability changes. The variants promote EXOSC3 exon 3 skipping, destabilize EXOSC3 and RNA exosome subunits, and trigger compensatory upregulation of DIS3 and other RNA-processing factors.

Key findings

  • RNA-seq of EXOSC3 G191C/+, G191D/+, and G191D/G191D cells versus isogenic controls found widespread differential transcript abundance: G191D/G191D had 7,880 significant transcripts (1,780 increased, 6,100 decreased; adjusted p ≤ 0.05), G191D/+ had 2,938 increased and 3,443 decreased, and G191C/+ had 3,229 increased and 3,602 decreased.
  • All G191 variants increased skipping of EXOSC3 exon 3; in G191D/G191D only ~50% of transcripts exhibited exon 3 splice-in compared to control, and G191D/+ showed ~25% of transcripts losing exon 3.
  • Global proteomics quantified 6,856 of 7,784 detected proteins and showed EXOSC3 reduced to fold changes of 0.475 (G191C/+), 0.45 (G191D/+), and 0.504 (G191D/G191D) relative to control; DIS3 was upregulated ~1.25-fold, while EXOSC10 protein decreased.
  • Molecular dynamics and λ-dynamics predicted EXOSC3 folding penalties of ~4–6 kcal/mol (discussion: 4.37–6.12 kcal/mol), with G191D more destabilizing than G191C; PISA showed significant destabilization of EXOSC1, EXOSC3, and MPP6 in G191D/G191D cells, and EXOSC1 and MPP6 in heterozygous lines.

Methods

  • HEK293T cells were edited by CRISPR/Cas9 homology-directed repair to generate EXOSC3 G191C/+, G191D/+, and G191D/G191D clonal lines plus isogenic controls, confirmed by Sanger sequencing.
  • Total RNA-seq used n = 4 biological replicates per genotype at an average depth of 259.82 ± 38.1 million reads; differential abundance was analyzed with DESeq2 (Wald test, Benjamini-Hochberg correction), and splicing with rMATS.
  • Proteomics used TMTpro 16plex on an Orbitrap Eclipse for global abundance and PISA thermal stability; structural analyses used MD and λ-dynamics simulations from PDB 6D6Q, and rescue experiments used HaloTag EXOSC3 overexpression, FACS, and global proteomics.

Limitations

  • The paper states that λ-dynamics analysis excludes possible reorganizational free-energy penalties needed to fold variant EXOSC3s into a binding-competent conformation, which would likely affect the true ΔΔGbind.
  • The paper notes that a more complete MPP6 structure could attenuate the observed changes in MPP6 α2.
  • Evident from the text: the main model is HEK293T cells, a non-neuronal line, and the G191C/+ line had a triploid allele frequency with two G191C copies and one parental EXOSC3 sequence, complicating simple heterozygous dosage interpretation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-17.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-17.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.
