Abstract
Abstract Because the contribution of genetic factors to the burden of breast cancer is not well investigated in Iran, we aimed to examine the prevalence of mutations in breast cancer susceptibility genes, BRCA1/2 and PALB2, and to investigate the predictive potential of hereditary breast cancer risk criteria for genetic testing in Iranian population. Next-generation sequencing was conducted on a population consisting of 299 and 125 patients with breast cancer, with and without hereditary cancer risk criteria for genetic testing, respectively. The pathogenic mutation frequency rate was 10.7% in patients with hereditary cancer criteria versus 1.6% in no criteria group (P = 0.0017). None of the 107 tested patients with only young age at onset (<40) criterion had a pathogenic mutation. Patients who had only a single heritable risk criterion [OR, 6.15; 95% confidence interval (CI), 1.26–58.59; P = 0.009] and patients with multiple heritable risk criteria (OR, 22.5; 95% CI, 5.19–201.31; P < 0.0001) had higher probabilities of carrying a mutation compared with no criteria group. Our results showed that young age at onset alone is not an indicator of hereditary breast cancer at least in the Iranian population. This is while women with multiple hereditary breast cancer risk criteria were enriched for BRCA1/2 mutations. Given such high risk of identification of a disease-causing mutation, multiple hereditary criteria should be regarded as a strong predictor for a hereditary breast cancer syndrome. These findings are important concerning the optimization of genetic counseling and furthermore establishing criteria for BRCA1/2 testing of the Iranian population.

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 it
