Abstract 38: Variations in ORAI1 gene associated with Kawasaki disease
Bibliographic record
Abstract
Kawasaki disease (KD; MIM611775) is a systemic vasculitis syndrome with unknown etiology which predominantly affects infants and children. Recent findings of susceptibility genes for KD have suggested up-regulation of Ca2+/NFAT pathway as one of the main pathophysiological processes in KD. In this study, we focused on ORAI1, a gene for a channel involved in store operated Ca2+ entry located on 12q24 where positive linkage signal was seen in our previous sib pair study of KD, and conducted a genetic association study. By re-sequencing 17.4kb of ORAI1 region for 94 subjects, we identified 37 variants with minor allele frequencies larger than 0.05. After selecting 9 tagging SNPs which represent 37 variants we performed an association study using 730 KD cases and 1315 controls. As a result, one tagging SNP located within exon2 showed nominal association (rs3741596; OR = 1.19, 95%CI 1.02~1.40, P = 0.028). The same trend of association was observed in an independent case control panel (1813 KD cases and 1097 controls, OR=1.22, 95% CI 1.06-1.40, P = 0.0056) and a significant P value was observed in a meta-analysis (OR = 1.21, 95%CI 1.09~1.34, P = 0.00041). Furthermore, we also found a rare 6 base-pair insertion polymorphism which cause elongation of proline repeat within N-terminal cytoplasmic domain of the ORAI1 protein was overrepresented in KD cases (rs78448924; OR = 3.91, 95%CI 1.30~11.80, P=0.010). These data indicate altered ORAI1 function confers susceptibility of KD and further highlight importance of the Ca2+/NFAT pathway in the disease pathogenesis.

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.
