A novel factor XI gene mutation associated with mild factor XI deficiency in a symptomatic patient
Bibliographic record
Abstract
Congenital factor XI deficiency is a rare condition, in which plasma factor XI levels correlate poorly with the severity of haemorrhage. The condition is typically characterized by post-traumatic bleeding. The factor XI gene is located on chromosome 4 and contains 15 exons. More than 80 mutations have so far been described. We describe a novel mutation in the factor XI gene associated with mild factor XI deficiency. The patient, who is of Irish descent, has a history of post-traumatic bleeding and was found to have a borderline factor XI deficiency. DNA sequence analysis of the factor XI gene revealed a novel T to A mutation at nucleotide 168 resulting in the substitution of the cysteine residue at codon 38 with a stop codon (Cys38STOP). The mutation predicts the premature termination of translation of factor XI mRNA resulting in a truncated, and probably unstable, factor XI protein. The presence of the mutation is consistent with the patient's borderline factor XI deficiency.

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.
