Naturally occurring splice variants dissect the functional domains of <scp>BHC80</scp> and emphasize the need for <scp>RNA</scp> analysis
Bibliographic record
Abstract
Pathogenic PHF21A variation causes PHF21A-related neurodevelopmental disorders (NDDs). Although amorphic alleles, including haploinsufficiency, have been established as a disease mechanism, increasing evidence suggests that missense variants as well as frameshift variants extending the BHC80 carboxyl terminus also cause disease. Expanding on these, we report a proposita with intellectual disability and overgrowth and a novel de novo heterozygous PHF21A splice variant (NM_001352027.3:c.[153+1G>C];[=]) causing skipping of exon 6, which encodes an in-frame BHC80 deletion (p.(Asn30_Gln51del)). This deletion disrupts a predicted leucine zipper domain and implicates this domain in BHC80 function and as a target of variation causing PHF21A-related NDDs. This extension of understanding emphasizes the application of RNA analysis in precision genomic medicine practice.

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.
