Torpedo Maculopathy Associated with NEXMIF Mutation
Bibliographic record
Abstract
Mutations in the neurite extension and migration factor (NEXMIF) gene are associated with X-linked intellectual disability. Thus far, all males reported with NEXMIF mutations have mild to profound intellectual disability with varying combinations of autistic features, poor or absent speech, epilepsy, facial dysmorphism, and strabismus. Affected females tend to have milder intellectual disability but severe, drug-resistant epilepsy. Here, we present a 32-month-old boy with a novel de novo frameshift NEXMIF pathogenic variant (p.Glu375ArgfsX21) who has mild motor delay, language delay, autistic features, and strabismus. In addition to these commonly described findings of NEXMIF mutations, his fundus exam revealed a very rare ophthalmologic abnormality, torpedo maculopathy. This finding has not previously been reported with NEXMIF mutation; however, on literature review, 7/15 males with NEXMIF mutations had other ophthalmologic abnormalities. This patient expands the phenotypic spectrum for males with NEXMIF mutations and suggests that NEXMIF may play an important role in ocular development.

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.
