Automatic Phenotyping of Patients on 2D Photography

An observational study in Dysmorphia, Orphan Diseases and Dysmorphies Craniofaciales, sponsored by Imagine Institute. Recruiting at 1 site in France. Per ClinicalTrials.gov, last updated 2026-01-12.

Registry
Congenital Abnormalities — the first condition term the registry derived for this study.

Rare Diseases
Why
  1. Congenital Abnormalities is a broad heading, used only when no more specific condition is named.
  2. The study's listed conditions name Rare Diseases.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The field of artificial intelligence is booming in medicine and in the field of diagnosis. The data can be varied: x-rays, pathology sections, or photographs.

It is considered that 30 to 40% of the 7000 rare diseases described to date cause craniofacial dysmorphia. Their detection sometimes requires the trained eye of a geneticist, because certain phenotypic traits are subtle. These diagnostic difficulties and the fact that certain diseases are extremely uncommon lead to considerable diagnostic delays

Lead sponsor

Imagine Institute is the lead sponsor of 31 studies on the registry; 15 are open to participants now.

Compared within Rare Diseases, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Congenital Abnormalities. The counts are of registry records indexed under each term, refreshed daily. How we classify →

Study population

Recruitment will be carried out either:

In Necker in the services of:

  • Medical genetics
  • Maxillofacial surgery / plastic surgery
  • Neurosurgery (functional craniofacial surgery unit)

Outside Necker:

  • In other national university hospitals: Lille (maxillofacial surgery department), Nantes (maxillofacial surgery department), Montpellier (clinical genetics department)
  • In other international university hospitals: London (GOSH, London, Professor Dunaway) and Bangkok (genetics department, Professor Porntaveetus)
  • In a private orthodontic practice

Eligibility criteria

The patient inclusion criteria are:

  • Patients followed in medical genetics,
  • Patients undergoing maxillofacial surgery, or craniofacial surgery as part of the management of a pathology, of genetic origin or not, associated with dysmorphism of the head and neck,
  • Patients for whom frontal and profile facial photographs are taken as part of their treatment.

The inclusion criteria for control subjects are:

  • Patients followed in maxillofacial surgery, for a disease other than a rare disease associated with dysmorphia in the head or neck: acute pathology (wound) or chronic (gynecomastia).
  • Patients for whom frontal and profile facial photographs are taken as part of their treatment.

The criteria for non-inclusion of patients are:

  • Patients who have undergone facial or skull surgery before the first photo was taken.
  • Person subject to a judicial safeguard measure.
  • People objecting to the reuse of their health data.

The criteria for non-inclusion of control subjects are:

  • Pathologies affecting facial symmetry (dental cellulitis, displaced fractures).
  • Patient followed for dysmorphic syndrome or in whom dysmorphic syndrome has been suspected.
  • Person subject to a judicial safeguard measure.
  • People objecting to the reuse of their health data.
