Severe FVII deficiency caused by a new point mutation combined with a previously undetected gene deletion
Bibliographic record
Abstract
A 3-week-old Caucasian female presented with severe unprovoked parenchymal cerebral haemorrhage. Her plasma factor VII (FVII) activity was <0.01 units/ml. FVII activities for her mother and sister were 0.65 units/ml and 0.51 units/ml, respectively, while her father's level was normal. These results indicated that the mother was heterozygous for a non-functional F7 gene that had also been inherited by the proband's sister. The proband's severe FVII deficiency was caused by a new mutation in her paternal F7 gene coupled with the inheritance of the non-functional maternal F7 gene. DNA sequence analysis revealed that the proband had apparent homozygosity for a novel single point mutation (g.3907G >A) changing the codon for Glu29 to Lys (E29K); neither parent had the E29K mutation. Because of the unlikelihood that the proband was homozygous for two identical new point mutations, the DNA sequence abnormality was more likely to have arisen from a single mutated gene on one allele and a F7 gene deletion on the other allele. Real time polymerase chain reaction (PCR) analysis confirmed that the proband had inherited a gene deletion that was present in the maternal side of the family. Subsequent clotting assays and real time PCR revealed that the maternal deletion also included the closely linked F10 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.
