EFFECT OFVARIATIONSIN ABCC2, CYP2C9, CYP2C19 & SCN2A GENESON TREATMENT RESPONSETO ANTICONVULSANTS- A SYSTEMATIC REVIEWAND META-ANALYSIS OF GENETIC ASSOCIATION STUDIES
Bibliographic record
Abstract
Objective: This study was aimed to determine the effect of genetic polymorphisms (non-synonymous, missense, and copy number variations) in ABCC2, CYP2C9, CYP2C19&SCN2A genes on treatment response to anticonvulsants. Methods: The search was carried out in PubMed, Scopus, Cochrane Central Register of Controlled Trials, Embase, LILACS, Google Scholar, MEDLINE, ScienceDirect, Web of Science, and the DOAJ database. Hardy Weinberg Equilibrium (HWE), New-Castle Ottawa scale value, Cochrane Review Manager 5.0 (&R 4.0.3,) and Rayyan QCRI are used for assessing data synthesis, risk of bias, heterogeneity assessment using I[2]statistics and calculating Inter-rater agreement respectively. Publication bias assessment was performed using Eggers test and the Funnel plot. For statistical analysis, random effects modeling was used to explain the association between genetic variations in ABCC2, CYP2C9, CYP2C19 & SCN2A genes related to drug resistance or treatment failure. Results: This meta-analysis includes a total of 29 studies. We found a greater risk of AED resistance in ABCC2rs2273697 genetic variations (OR=1.51 [ 0.93-2.47], p value=0.03 at 95% CI), ABCC2 rs3740066 genetic variation has a greater possibility of AED resistance was seen in pooled population (OR= 0.85 [0.12-5.85], p-value<0.01 at 95% CI), risk of drug resistance was increased by ABCC2 rs717620 polymorphism. (OR =2.13, [1.02-4.44], p-value<0.01 at 95% CI), CYP2C9 rs1799853 polymorphism had a significant increase in AED resistance (OR =1.27, [0.49-3.32] p-value<0.01 at 95% CI), CYP2C9 rs1057910 polymorphism. (OR= 0.74, [0.32-1.70] p-value 0.01 at 95% CI), CYP2C19 rs4244285 polymorphism. (OR= 0.68, [0.29-1.62], p value=0.02 at 95% CI), SCN2A rs2304016 polymorphism. (OR= 1.20, [0.48-3.05], p value<0.01 at 95% CI), SCN2Ars17183814 polymorphism. (OR =1.51, [1.12-2.03], p value=0.30 at 95% CI). Conclusions:Gene polymorphisms play a key role in epilepsy development and therapeutic efficacy, and could have greater impact treatment outcomes.

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.
