The Dyslexia-associated gene <i>KIAA0319L</i> is involved in neuronal migration in the developing chick visual system
Bibliographic record
Abstract
The gene KIAA0319-Like (KIAA0319L) is thought to confer susceptibility for developmental dyslexia. Dyslexia may be caused by alterations in neuronal migration, and in utero knockdown of KIAA0319L in rats indicated migration errors. However, studies carried out with KIAA0319L knockout mice did not reveal an altered neuronal migration phenotype. Gene knockout may activate compensatory mechanisms to buffer against genetic mutations during development. Here we assessed the role of KIAA0319L on migrating neurons in the chick developing tectum. Whole mount in situ hybridization was performed for KIAA0319L on embryonic day (E)3 - E5 chick embryos and in situ hybridization on sections was performed at later stages. The specificity and efficiency of engineered microRNA (miRNA) constructs targeting KIAA0319L for knocking down KIAA0319L were verified. miRNAs were electroporated into E5 chick optic tecta. Our studies demonstrate that KIAA0319L is expressed in the developing chick visual system, as well as in the otic vesicles. Knockdown of KIAA0319L in the optic tectum results in abnormal neuronal migration, strengthening the argument that KIAA0319L is involved in this developmental process.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
