Abstract
OBJECTIVE: To report the prenatal presentation with dilated cardiomyopathy of methylmalonic aciduria and homocystinuria, cblC type [cobalamin C (cblC) deficiency] (MIM 277400). METHOD: We describe a boy with cblC deficiency who presented prenatally with fetal ultrasound findings of dilated cardiomyopathy and growth restriction. RESULTS: Dilated cardiomyopathy and growth retardation were detected in the third trimester of an initially uncomplicated pregnancy. Investigations were negative for chromosomal and other known causes. Growth restriction persisted but fetal heart function improved. Postnatal biochemical evaluation revealed combined methylmalonic acidemia and homocystinemia. Molecular investigations confirmed cblC deficiency. Initiation of treatment was followed by rapid clinical improvement. CONCLUSION: Prenatal dilated cardiomyopathy can be the presenting sign of cblC deficiency. Inborn errors of metabolism should be considered in the investigation of prenatally diagnosed dilated cardiomyopathy in view of the possible impact on treatment and future reproductive options, in some of these conditions.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
