Heterozygous missense mutation of the fibrinogen gene associated with cryptogenic liver disease in a 15-months-old Canadian caucasian child
Bibliographic record
Abstract
Hepatic fibrinogen storage disease is an uncommon autosomal dominant hereditary illness marked by hypofibrinogenemia and the accumulation of variant fibrinogen in the hepatic endoplasmic reticulum. We present an asymptomatic 15-month-old male with elevated liver enzymes. Test results indicate hypofibrinogenemia. The liver biopsy revealed circular eosinophilic inclusion bodies within the hepatocyte cytoplasm. After diastase pretreatment, the inclusion bodies did not stain using the periodic acid – Schiff procedure. Ultrastructural examination revealed the characteristic fibrinogen storage curvilinear inclusions. Sequence analysis using the Blueprint Genetics (BpG) FLEX Bleeding Disorder/Coagulopathy Panel identified a heterozygous missense variant FGG c.1075 G>C, p. (Gly359Arg). Thus, the patient was diagnosed with hepatic fibrinogen storage disease. Our findings suggest that in patients with asymptomatic elevated liver enzymes presenting with unanticipated hypofibrinogenemia, hepatic fibrinogen storage disorder must be included in the differential diagnosis. Furthermore, our results underscore the significance of molecular diagnosis in patients diagnosed with cryptogenic liver disease.

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.
