Abstract

fetched live from OpenAlex

Heterozygous de novo variants in the autophagy gene, WDR45, are found in beta-propeller protein-associated neurodegeneration (BPAN). BPAN is characterized by adolescent onset dementia and dystonia; 66% patients have seizures. We asked whether WDR45 was associated with developmental and epileptic encephalopathy (DEE). We performed next generation sequencing of WDR45 in 655 patients with developmental and epileptic encephalopathies. We identified 3/655 patients with DEE plus 4 additional patients with de novo WDR45 pathogenic variants (6 truncations, 1 missense); all were female. Six presented with DEE and 1 with early onset focal seizures and profound regression. Median seizure onset was 12 months, 6 had multiple seizure types, and 5/7 had focal seizures. Three patients had magnetic resonance susceptibility-weighted imaging; blooming was noted in the globus pallidi and substantia nigra in the 2 older children aged 4 and 9 years, consistent with iron accumulation. We show that de novo pathogenic variants are associated with a range of developmental and epileptic encephalopathies with profound developmental consequences.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
