Abstract

Mutations in the actively expressed, maternal allele of the imprinted KCNK9 gene cause Birk-Barel intellectual disability syndrome (BBIDS). Using a BBIDS mouse model, we identify here a partial rescue of the BBIDS-like behavioral and neuronal phenotypes mediated via residual expression from the paternal Kcnk9 ( Kcnk9 pat ) allele. We further demonstrate that the second-generation HDAC inhibitor CI-994 induces enhanced expression from the paternally silenced Kcnk9 allele and leads to a full rescue of the behavioral phenotype suggesting CI-994 as a promising molecule for BBIDS therapy. Thus, these findings suggest a potential approach to improve cognitive dysfunction in a mouse model of an imprinting disorder.

  • CI-994 is a cognitive enhancer / improves cognitive function.

    “CI-994 can cross the blood–brain barrier and is a cognitive enhancer.”

    From CI-994 is a dual modulator of class I HDACs and Wnt/β-catenin signaling for the treatment of Alzheimer's disease (2026) · cites this paper as [22]

    The Results section ('CI-994 rescues the behavioral phenotype of Kcnk9KOmat animals'; page unavailable) reports improved Y-maze working-memory performance in a mouse model after CI-994 treatment. The same section reports no significant Y-maze improvement in wild-type mice, so the unqualified description of CI-994 as a cognitive enhancer is broader than the evidence. The paper also reports that administered CI-994 reaches the brain, consistent with blood–brain barrier passage. (LLM, conf=0.87)

  • CI-994 is a molecular memory aid and promotes memory formation and cognitive function in vivo.

    “CI-994 is a molecular memory aid and promotes memory formation and cognitive function in vivo [9, 17, 21–24].”

    From CI-994 is a dual modulator of class I HDACs and Wnt/β-catenin signaling for the treatment of Alzheimer's disease (2026) · cites this paper as [22]

    The Results section, “CI-994 rescues the behavioral phenotype of Kcnk9KOmat animals” (page not provided), reports improved Y-maze performance, a measure of working memory, in a mouse model of Birk-Barel syndrome. It reports no significant working-memory improvement in wild-type mice. The study therefore supports an in vivo rescue of impaired working memory, but not the broader claim that CI-994 generally promotes memory formation or cognitive function. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • CI-994 alleviates cognitive deficits in mouse models of neurodegenerative disorders.

    “CI-994 acts as a memory enhancer and alleviates cognitive deficits in mouse models of neurodegenerative disorders [9, 17, 21–24].”

    The Results section (“CI-994 rescues the behavioral phenotype of Kcnk9KOmat animals”; page not available) reports improved Y-maze working-memory performance after CI-994 treatment in a mouse model of Birk-Barel intellectual disability syndrome. It does not establish relief of cognitive deficits in mouse models of neurodegenerative disorders, and the Discussion reports no significant working-memory effect in wild-type mice. (LLM, conf=0.88)

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.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
