The impact of GAB2 genetic variations on cerebrospinal fluid markers in Alzheimer’s disease
Bibliographic record
Abstract
Background: Growth factor receptor-bound protein-associated binding protein 2 gene (GAB2) has been regarded as one of the susceptibility gene associated with Alzheimer’s disease (AD). However, the role of GAB2 polymorphisms on cerebrospinal fluid (CSF) proteins in AD continuum remains unclear. Methods: We evaluated the connection between four single nucleotide polymorphisms (SNPs) of GAB2 and AD-related CSF biomarkers including amyloid β (Aβ), total tau (T-tau) and phosphorylated tau (P-tau) level in 627 Alzheimer’s Disease Neuroimaging Initiative (ADNI) subjects. Results: rs1385600 and rs1007837 were significantly associated with all the three biomarkers in CSF (rs1385600: Aβ Pc =0.0112, T-tau Pc =0.0356, P-tau Pc =0.0116; rs1007837: Aβ Pc =0.0058, T-tau Pc =0.0278, P-tau Pc =0.0231). rs2373115 only showed significant association with Aβ and P-tau (Aβ, Pc=0.0398, P-tau, Pc=0.0329). rs10793294 showed no significant association with all the three biomarkers. Conclusions: Our study suggested that GAB2 variants were significantly associated with the level of the three CSF biomarkers, which further supported that GAB2 genetic variation modulates AD risk via the alteration of both Aβ and tau pathology.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
