Abstract

fetched live from OpenAlex

Genetic disorders commonly share features such as developmental delays, cognitive impairment, and behavioral challenges, yet many conditions also present unique dysmorphic features that distinguish them. Performing a thorough medical and family history and a detailed physical exam with attention to dysmorphic features is often the first step toward arriving at a genetic diagnosis. Synthesizing a differential diagnosis from the information gathered helps to guide the genetic testing strategy. Challenges to recognizing a disorder include the breadth of the clinician's prior experience, the lack of distinctive dysmorphology or overlapping dysmorphology in some conditions, atypical presentations, and difficulties identifying phenotypes across different ancestries. In cases where such challenges exist, advanced facial recognition technology can help the consulting expert by directing a more efficient test strategy. We present 17 cases involving 19 patients, including one pair of affected siblings and one case involving a child and her affected mother, for which DeepGestalt, the technology powering Face2Gene, changed medical geneticists' testing decisions. These cases illustrate how this form of artificial intelligence can provide clinical utility through influencing providers' genetic testing recommendations in real time.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
