Does the NPHS1 c.349G>A Polymorphism Affect Outcomes in FSGS Patients?
Bibliographic record
Abstract
Background: Treatment of steroid-resistant nephrotic syndrome with a focal segmental glomerulosclerosis (FSGS) histological diagnosis can be challenging, particularly in the presence of ciclosporin resistance. The importance of mutations in genes encoding the structural proteins of podocytes has been recently recognized and may influence medical decision-making. The c.349G>A variant of the NPHS1 gene has been associated with a poorer prognosis in IgA nephropathy and nephrotic syndrome. Case Diagnosis/Treatment: To study the potential association of the NPHS1: c.349G>A sequence variant with renal disease, we analyzed five children in whom this variant had been identified and who all presented with nephrotic syndrome and the histological diagnosis of FSGS. Although this sequence variant was present in all cases, one patient had steroid-responsive nephrotic syndrome without relapse following standard initial therapy, three responded to a variety of treatments, and one patient was unresponsive. Conclusion: The NPHS1: c.349G>A sequence variant may either be independent of, or a modifying agent in, the progression of the disease, and does not preclude these and similar patients from appropriate treatment and entry into clinical trials. Larger trials are needed to evaluate the therapeutic response and long-term outcome of FSGS patients with different NPHS gene mutations.

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.
