Retrospective Analysis of Canadian Adults with Tuberous Sclerosis Complex
Bibliographic record
Abstract
ABSTRACT: Background: Our study goal was to characterize the relative frequencies of molecular and phenotypic traits of tuberous sclerosis complex (TSC) in a Canadian adult population. Previous studies have sought to identify TSC-related genotypic and phenotypic trends in pediatric cohorts, but little is known about clinical manifestations and severity when it presents in adults. Methods: We conducted a retrospective chart review of adult patients seen at the TSC clinic at the University Health Network genetics clinics (Toronto, Ontario) to compare trends in the relative frequency of TSC manifestations with genotype. Results: Fifty-one patients were eligible for this study. Eight patients had a pathogenic/likely pathogenic variant in the tuberous sclerosis complex 1 ( TSC1) gene, 18 had a tuberous sclerosis complex 2 ( TSC2) pathogenic/likely pathogenic variant, 6 patients had multiple variants identified in TSC1 / TSC2 or TSC2 / PKD1 , 11 had no mutation identified (NMI) and 8 had no genetic testing done. Patients with a pathogenic/likely pathogenic variant in TSC2 presented with an increased involvement of multiple systems and a higher frequency of TSC-related manifestations relative to the other mutation groups. Conclusion: Previous studies comparing the wide phenotypic variability with TSC genotype have mainly comprised pediatric cohorts. With a focus on adults, we found trends to be similar across previous literature. An informed multidisciplinary approach should be taken to ensure proper surveillance and management of adults with TSC until a correlation between genotype and phenotype, especially past infancy, is better understood.

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; both teacher heads agree on what is shown here.
