Expansion of the <scp>GLE1</scp>‐associated arthrogryposis multiplex congenita clinical spectrum
Bibliographic record
Abstract
Mutations in GLE1 cause two recessive subtypes of arthrogryposis multiplex congenita (AMC), a condition characterized by joint contractures at birth, and all previously reported patients died in the perinatal period. GLE1 related AMC has been almost exclusively reported in the Finnish population and is caused by a relatively common pathogenic splicing mutation in that population. Here, we report two non-Finnish brothers with novel compound heterozygous splicing mutations in GLE1, one of whom has survived to 12 years of age. We also demonstrate low levels of residual wild type transcript in fibroblasts from the surviving brother, suggesting that this residual wild-type transcript may contribute to the relatively longer-term survival in this family. We provide a detailed clinical report on the surviving patient, providing the first insight into the natural history of this rare neuromuscular disease. We also suggest that lethal congenital contracture syndrome 1 (LCCS1) and lethal arthrogryposis with anterior horn disease (LAAHD), the two AMC subtypes related to GLE1, do not have sufficient clinical or molecular differentiation to be considered allelic disorders. Rather, GLE1 mutations cause a variable spectrum of AMC severity including a non-lethal variant described herein.

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.
