Epilepsy due to a <i>MED25</i> Homozygous Pathogenic Founder Variant
Bibliographic record
Abstract
Previous reports have described a spectrum of clinical phenotypes in patients with MED25 pathogenic variants. One specific phenotype is the Basel-Vanagaite-Smirin-Yosef syndrome, which is a rare, autosomal recessive disorder characterized by a wide range of symptoms including eye abnormalities, cardiac abnormalities, palatal abnormalities, intellectual disability, and epilepsy. Although epilepsy appears to be common, the electroclinical phenotypes of patients with Basel-Vanagaite-Smirin-Yosef syndrome have not been well described. Here, we report 3 Basel-Vanagaite-Smirin-Yosef syndrome patients from 2 families of Lebanese descent with a homozygous MED25 founder variant from Alberta Children's Hospital, Calgary, Alberta. We describe in detail electroclinical phenotypes in each of these 3 patients. These patients developed seizures with onset between 2 and 3 years of age, multifocal and generalized discharges, as well as photoparoxysmal responses on electroencephalogram. We review the relevance of these epilepsy findings in the context of other published reports of Basel-Vanagaite-Smirin-Yosef syndrome.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
