Refinement of causative genes in monosomy 1p36 through clinical and molecular cytogenetic characterization of small interstitial deletions
Bibliographic record
Abstract
Monosomy 1p36 is the most common terminal deletion syndrome seen in humans, occurring in approximately 1 in 5,000 live births. Common features include mental retardation, characteristic dysmorphic features, hypotonia, seizures, hearing loss, heart defects, cardiomyopathy, and behavior abnormalities. Similar phenotypes are seen among patients with a variety of deletion sizes, including terminal and interstitial deletions, complex rearrangements, and unbalanced translocations. Consequently, critical regions harboring causative genes for each of these features have been difficult to identify. Here we report on five individuals with 200-823 kb overlapping deletions of proximal 1p36.33, four of which are apparently de novo. They present with features of monosomy 1p36, including developmental delay and mental retardation, dysmorphic features, hypotonia, behavioral abnormalities including hyperphagia, and seizures. The smallest region of deletion overlap is 174 kb and contains five genes; these genes are likely candidates for some of the phenotypic features in monosomy 1p36. Other genes deleted in a subset of the patients likely play a contributory role in the phenotypes, including GABRD and seizures, PRKCZ and neurologic features, and SKI and dysmorphic and neurologic features. Characterization of small deletions is important for narrowing critical intervals and for the identification of causative or candidate genes for features of monosomy 1p36 syndrome.

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.
