Evidence for the absence of mutations at GJB3, GJB4 and LOR in progressive symmetrical erythrokeratodermia
Bibliographic record
Abstract
BACKGROUND: Progressive symmetrical erythrokeratodermia (PSEK) is a rare inherited cornification disorder characterized by symmetrical erythematous hyperkeratotic plaques. The genetic basis for PSEK is not clear. PSEK shares many clinical features with erythrokeratodermia variabilis (EKV), which is associated with mutations in genes coding for gap junction beta (GJB) 3 and 4. A mutation in the loricrin gene (LOR) was found in patients with PSEK, who were members of a family with Vohwinkel syndrome. It would therefore be of interest to determine if PSEK is also caused by mutations in these genes. AIM: To examine the mutation status of GJB3, GJB4 and LOR in patients with PSEK and in control subjects. METHODS: Genomic DNA samples from 25 patients with PSEK and 56 healthy controls were examined by sequencing analysis of the coding sequences of GJB3, GJB4 and LOR. RESULTS: There were no mutations found in any of these three genes. CONCLUSIONS: PSEK is a disorder distinct from EKV, and the true pathogenesis of PSEK remains unknown.

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.
