Experience of carrier couples identified through a population‐based carrier screening pilot program for four founder autosomal recessive diseases in Saguenay–Lac‐Saint‐Jean
Bibliographic record
Abstract
A pilot population-based carrier screening program started in 2010 in the Saguenay-Lac-Saint-Jean region of Quebec, Canada, for four recessive diseases with local founder effects (tyrosinemia type I, autosomal recessive spastic ataxia of Charlevoix-Saguenay, congenital lactic acidosis, and Andermann syndrome). OBJECTIVES: The objective of this study was to describe the experience of carrier couples identified through this program. METHODS: Semi-structured interviews were performed with carrier couples. Thematic analysis of interview transcripts was performed to identify emerging themes. RESULTS: Interviews were performed with 15 carrier couples (56% response rate). Carrier couples had little knowledge about the target diseases before being identified as carriers, despite pre-test education sessions. The main motivation for screening was a recommendation by a peer who had been screened, even for those with a positive family history of one of the target conditions. Couples perceived themselves at low risk of being a carrier couple, whatever their family history. Being found to be a carrier couple was initially a shock, illustrating how ill prepared they were for such a result, but carrier couples appreciated knowing their status. CONCLUSION: Our results emphasize the informational needs of couples to make informed decisions and the importance of post-test counseling for those with positive results. Our findings can inform counseling procedures in expanded carrier screening. © 2017 John Wiley & Sons, Ltd.

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.
