Evidence layer

Claim by claim

The article's claims are listed below. Without a confirmed source study, they have not been assessed as supported or unsupported.

Claim 1 of 6Not checkedUsing a mouse model of DDX3X syndrome, the researchers discovered that motor deficits depend on a specific brain circuit connecting the cortex with a nucleus in the brainstem.View evidenceHide evidence

Not checked

No source study was confirmed for this article. This claim remains unverified, rather than assessed as supported or unsupported.

Claim 2 of 6Not checkedAn early intervention can improve motor trajectories, with lasting improvements in motor performance that persisted into adulthood.View evidenceHide evidence

Not checked

No source study was confirmed for this article. This claim remains unverified, rather than assessed as supported or unsupported.

Claim 3 of 6Not checkedThe syndrome is a genetic form of intellectual disability and autism that primarily affects girls and women, and a genetically engineered mouse model showed altered morphology and activity of the relevant cortical neurons.View evidenceHide evidence

Not checked

No source study was confirmed for this article. This claim remains unverified, rather than assessed as supported or unsupported.

Claim 4 of 6Not checkedSuppressing the DDX3X gene in only the cortical neurons projecting to the brainstem induced motor deficits, specifically in female mice.View evidenceHide evidence

Not checked

No source study was confirmed for this article. This claim remains unverified, rather than assessed as supported or unsupported.

Claim 5 of 6Not checkedJuvenile mutant mice exposed to the motor intervention had alleviated motor deficits as adults.View evidenceHide evidence

Not checked

No source study was confirmed for this article. This claim remains unverified, rather than assessed as supported or unsupported.

Claim 6 of 6Not checkedThe authors say the work suggests there is still plasticity that can be harnessed for therapeutic intervention and that future studies may reveal new therapeutic targets.View evidenceHide evidence
