Abstract

fetched live from OpenAlex

Purpose: The Saguenay-Lac-Saint-Jean, Haute-Côte-Nord, and Charlevoix regions in Canada have a high prevalence of 4 autosomal recessive diseases with high morbidity and/or reduced life expectancy. As a result, a carrier screening program (CSP) was developed in 2010 and has been ongoing since. The program's purpose is to provide information and carrier screening for individuals having a higher probability to have an affected child to allow for informed decision making regarding reproductive choices. This publication provides an overview of the CSP, shares its results, and discusses the growing needs for expanding genetic testing and counseling. Methods: In 2018, the CSP transitioned from a regional to a provincially available program, supported by an innovative home self-sampling kit that can be requested online and returned by mail for analysis. For the purpose of this study, CSP data from 2010 to 2022 were extracted and analyzed. Results: = 116) were offered a subsequent appointment in a genetics clinic to further discuss the result, its potential implications, and available reproductive options. The heterozygote frequencies for the tested conditions ranged from 1 in 18 to 1 in 28. Conclusion: The relatively inexpensive method could be applied to other populations with a high prevalence of certain autosomal recessive diseases. Given the program's results, we must consider adding the screening of other prevalent recessive conditions to the CSP.

Not 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.
