Refractory and Fatal Presentation of Severe Autoimmune Hemolytic Anemia in a Child With the DNASE1L3 Mutation Complicated With an Additional DOCK8 Variant
Bibliographic record
Abstract
Various autoimmune diseases may be associated with primary immune deficiencies. We reported a case with a loss-of-function mutation in DNASE1L3, a gene described previously in families with systemic lupus erythematosus. In addition, the patient showed a novel homozygous missense variant in DOCK8, a gene known to be responsible for the hyper-IgE recurrent infection syndrome (HIES). A 3-year-old girl born to consanguine parents presented with chronic urticarial rash, hemolytic anemia, pulmonary hemorrhage, and hypovolemic shock findings. She had a low hemoglobin level, a positive direct antiglobulin test, antinuclear antibody and anti-double stranded DNA, low C3 and C4, third-degree tricuspid regurgitation, and severe enlargement of the right ventricle on echocardiography, suggesting pulmonary embolism. Despite treatment with intravenous immunoglobulin, pulse metilprednisolone, rituximab, and supportive treatment for shock, the patient died on the seventh day. Whole-exome sequencing indicated a homozygous stop variant c.537G>A (p. Trp179Ter) in DNASE1L3. In addition, a possibly pathogenic homozygous missense variant in the HIES gene DOCK8 was detected. The occurrence of potentially clinically relevant, genetic variants in several genes posed various challenges with respect to diagnosis, treatment, and prognosis.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
