Women heterozygous forNALP7/NLRP7 mutations are at risk for reproductive wastage: report of two novel mutations
Bibliographic record
Abstract
Familial recurrent hydatidiform moles are a rare recessive condition in which molar tissues have biparental contribution to their genome. One maternal locus responsible for this condition has been mapped to 19q13.4 and the causative gene, NALP7, identified (HUGO-approved nomenclature is now NLRP7). Here we report a first stop codon, c.295G>T (p.Glu99X) and a missense mutation, c.1970A>T (p.Asp657Val) in NLRP7 in two sisters with RHMs. We found these two mutations and a previously reported one, c.2078G>C (p.Arg693Pro) in a homozygous state, in males with normal reproductive outcomes. This suggests that NLRP7 is not required for normal spermatogenesis. The mother of the patients is heterozygous for Glu99X and had one stillbirth and three normal pregnancies. Our data on this new family and on heterozygous women from previously reported families indicate that women heterozygous for NLRP7 mutations are at risk for reproductive wastage without the manifestation of molar phenotype.

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.
