A fourth case of Feingold syndrome type 2: psychiatric presentation and management
Bibliographic record
Abstract
Feingold syndrome (FGLDS1) is an autosomal dominant disorder caused by mutations in the MYCN oncogene on the short arm of chromosome 2 (2p24.1). It is characterised by microcephaly, digital abnormalities, oesophageal and duodenal atresias, and often learning disability or mental retardation. In 2011, individuals sharing the skeletal abnormalities of FGLDS1 but lacking mutations in MYCN, were found to harbour hemizygous deletions of the MIR17HG gene on chromosome 13q31.3. These individuals share many of the characteristics of FGLDS1 except for gastrointestinal atresia. The condition was termed Feingold syndrome type 2 (FGLDS2). We describe the presentation and management of a fourth known case of FGLDS2 in an 18-year-old girl with microcephaly, short stature, mildly dysmorphic features, digital malformations and significant cognitive and psychiatric symptoms. Comparative genomic hybridisation array testing confirmed a 7.4 Mb microdeletion in chromosome region 13q31.1q.31.3 corresponding to the MIR17HG 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.
