Abstract

fetched live from OpenAlex

ABSTRACT The underlying cause for renal and uterine agenesis remains unknown in many cases, whereas recurrence in some families strongly suggests the involvement of genetic factors. Here, we identify 5 affected individuals from 3 families with phenotypes including bilateral or unilateral renal agenesis/hypoplasia, along with variable congenital uterine anomalies and costovertebral defects associated with heterozygous deleterious variants in NR6A1 . The variant spectrum includes both inherited missense as well as de novo loss of function, with the latter associated with a perinatal lethal phenotype characterized by bilateral renal agenesis. In vitro studies demonstrated partial loss-of-function for both missense variants. To investigate the role of NR6A1 in development, CRISPR-Cas9 knockout zebrafish models targeting the orthologues nr6a1a and nr6a1b were generated. Mutants recapitulate the human phenotype, exhibiting impaired kidney development, including pronephros segmentation defects and adult kidney hypoplasia, along with axial skeletal abnormalities, cloacal anomalies, and disrupted anteroposterior expression of posterior hox genes. This study provides strong evidence linking NR6A1 heterozygous loss-of-function variants to renal, uterine and costovertebral defects in humans.

Not 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.
