The finding that global but not cortical-specific P/Q deletion increases thalamic neurogenesis and β-catenin/Lef1 signaling reveals an unexpected developmental …

This work suggests SYNGAP1's non-synaptic role may represent a broader pattern among ASD-associated synaptic genes. Systematic investigation of other synaptic A…

The authors suggest tauopathy may explain brain imaging findings of atrophy in ASD/ID children, but this mechanistic link is not established. Understanding this…

While the study tested 5 of 16 autism genes and found consistent migration defects, it remains unknown whether this phenotype generalizes to other high-confiden…

The abstract establishes that neuronal activity triggers PGC-1α-mediated maturation but doesn't explain the upstream signaling mechanisms linking activity to PG…

The study identifies eight forebrain genes upregulated in Asxl1 knockout that correlate with midline defects, but doesn't establish how their dysregulation mech…

The study identifies consistent midline brain abnormalities (corpus callosum defects, anterior commissure hypoplasia, midbrain shortening) in 38-70% of patients…

While Mfsd2a deficiency causes severe microcephaly in mice and humans, the cellular and molecular pathways connecting lipid transport defects to impaired brain …

The study identified 13 diverse genes causing CP but doesn't explore shared pathophysiological mechanisms. Understanding convergent pathways could reveal therap…

The abstract notes that SWI/SNF mutations cause both cancer and neurodevelopmental disorders, but doesn't explain why the same genetic defects produce such dive…

The study demonstrates that TopIIbeta is critical for neurite outgrowth using inhibitors and knockout models, but the precise molecular pathway remains unexplai…

The abstract reveals that mCH accumulates exclusively in neurons during fetal to young adult development, becoming the dominant methylation form in human neuron…

The abstract identifies mTOR hyperactivation as disrupting multiple cellular processes but doesn't explain the mechanistic connections between mTOR signaling an…

The study shows that five autism genes (SYNGAP1, CHD8, SCN2A, CHD2, DYRK1A) all disrupt enteric neuron migration when targeted, but the specific molecular pathw…

The abstract mentions that pathogenic human mutations weaken Syncrip's phase-separation capability but doesn't explain the molecular mechanisms or how this rela…

The study identifies that Slc35a2 deficiency disrupts corticogenesis by delaying radial migration from the subventricular zone, but the specific molecular pathw…

The study shows MEF2C is crucial for neuronal differentiation and proper cortical layering, but the specific downstream targets and signaling pathways remain un…

The study identifies likely pathogenic variants in these three genes but provides no mechanistic explanation for how they contribute to ASD symptoms. Understand…

The abstract states that Reelin's action in pattern formation is unknown, only speculating it may trigger recognition-adhesion among neurons. Understanding this…

The study shows ASXL1 directly interacts with SIX3 and they co-regulate target genes, but the chromatin-level mechanism is unexplained. Understanding this epige…

The abstract states that Reelin is required for proper neuronal lamination and pattern formation, but explicitly notes that 'the action of Reelin is unknown.' U…

CP masqueraders showed 60% diagnostic yield versus 29% in cryptogenic CP, suggesting distinct underlying genetic architectures. This unexplained difference coul…

The authors suggest the risk allele connects to fewer brain MT1 melatonin receptors and slower socioemotional/communication development, but the mechanistic pat…

While mutations in LIS1 and DCX cause type 1 lissencephaly 'most probably due to defective nucleokinesis,' the specific mechanisms remain unclear. Both proteins…

The abstract notes that while core components (VLDLR, ApoER2, Src/Fyn, Dab1) are common to most Reelin functions, other effectors are task-specific. The molecul…

While the study shows Syncrip recruits stabilization complexes via phase separation to maintain transcription factor expression, the identity and composition of…

The abstract states that children are much more susceptible to OP neurotoxic effects than adults, but the developmental or physiological basis for this age-depe…

The abstract identifies UBE3A secretion as a newly discovered pattern but provides no mechanistic explanation. Understanding how an E3 ligase is secreted and fu…

Despite identifying 806 direct SIX3 targets, only 8% show concordant expression changes when ASXL1 is lost. This selectivity suggests unknown factors determine …

The study found significant differences in hypotonic-ataxic subtype prevalence between classification groups (p=0.01) but provides no mechanistic explanation. U…

The study identifies PPAR- and NF-κB-mediated modes of action but doesn't elucidate the precise molecular mechanisms linking PFAS exposure to these pathway alte…

GenX exposure before differentiation causes lasting alterations in mature cortical neurons, but the molecular memory mechanisms enabling this developmental prog…

The authors identify disrupted cholinergic signaling as the primary neurotoxic mechanism and suggest Gap43/mTOR involvement, but the mechanistic connection betw…

The study finds genetic variants in only 35% of cases using state-of-the-art genomic approaches, leaving the majority unexplained. This substantial gap suggests…

The abstract notes that Cdk5 mutations cause migration defects compatible with defective nucleokinesis, but also likely affect leading edge formation. The dual …

The abstract notes that Cdk5 mutations result in migration defects 'compatible with defective nucleokinesis, although an effect on leading edge formation is als…

The abstract describes distinct developmental versus postdevelopmental functions of Reelin but doesn't explain how the same signaling pathway mediates such diff…

The syndrome shows a characteristic symmetrical, predominantly fronto-parietal distribution of polymicrogyria and specific calcification patterns in deep gray m…

While the study identifies 52 genes associated with both PFAS exposure and immune outcomes, the functional relationships and causal pathways linking these genes…

The abstract describes two distinct modes of leading edge extension but only suggests variation relates to extension rate. The molecular switches controlling mo…

The selective impact on differentiation while preserving proliferation and survival suggests MEF2C acts at specific developmental stages. Understanding this tem…

The abstract identifies structural and functional changes in specific hippocampal subfields but doesn't explain how CA1 versus dentate gyrus dysfunction maps to…

The study identifies Syncrip as regulating Notch signaling for RGC fate determination, but how this integrates with other known temporal patterning systems in c…
