Börjeson-Forssman-Lehmann Syndrome Due to a Novel Plant Homeodomain Zinc Finger Mutation in the PHF6 Gene
Bibliographic record
Abstract
The Börjeson-Forssman-Lehmann syndrome is an X-linked mental retardation disorder caused by mutations in the PHF6 gene. The PHF6 gene contains 2 plant homeodomain zinc fingers, suggesting a role for the protein in chromatin remodeling. In this study, the authors report on a Finnish family with a classical Börjeson-Forssman-Lehmann syndrome phenotype caused by a G to T nucleotide substitution at position 266 within exon 4 within the PHF6 gene (c.266G>T). The resulting glycine to valine (p.G89V) change corresponds to a highly conserved residue within the first plant homeodomain zinc finger domain. This is a novel change that adds to the number of plant homeodomain zinc finger mutations identified, such that 23% of all Börjeson-Forssman-Lehmann syndrome mutations lie within this motif. Moreover, it highlights the functional importance of plant homeodomain zinc finger motifs to human disease and more specifically to PHF6 function.

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.
