Geroderma osteodysplastica maps to a 4 Mb locus on chromosome 1q24
Bibliographic record
Abstract
Important insights into the etiology of osteoporosis have been gained by the study of single gene disorders, including osteogenesis imperfecta. We report on the genetic mapping of geroderma osteodysplastica (GO), a rare autosomal recessive disorder of the connective tissue, characterized by wrinkly skin and severe osteoporosis. We undertook autozygosity mapping in one Libyan and four consanguineous Pakistani families with a total of 10 affected individuals to define a 4 Mb homozygous region on chromosome 1q24, which harbors the GO causative gene. No obvious candidate genes that encode known protein constituents of the extracellular matrix are found in the linked region. Importantly, our study demonstrates that GO is not allelic to wrinkly skin syndrome caused by mutations in ATP6V0A2.

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.
