Broadening the ciliopathy spectrum: Motile cilia dyskinesia, and nephronophthisis associated with a previously unreported homozygous mutation in the <i>INVS</i>/<i>NPHP2</i> gene
Bibliographic record
Abstract
Nephronophthisis associated ciliopathies (NPHP-AC) are a group of phenotypically related conditions that include Joubert syndrome, Meckel syndrome, nephronophthisis (NPHP), and Senior-Loken syndrome. We report on a male fetus with prenatal ultrasound findings at 24 weeks of gestation of anhydramnios, large and echogenic kidneys and situs inversus totalis. Histopathology revealed nephronophthisis and tracheal mucosa electron microscopy revealed ciliary dysgenesis. DNA analysis of the NPHP genes showed a previously unreported homozygous mutation, p.Arg603* (c.1078+1G>A), in the INVS/NPHP2 gene. This mutation is thought to abolish the splice donor site for exon 8, which likely disrupts the normal splicing of the INVS/NPHP2 gene.

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.
