Optical genome mapping to find genetic causes of congenital orofacial clefts
Official title: Study of Congenital Orofacial Clefts by Implementing Optical Genome Mapping
Run by Centre Hospitalier Universitaire, Amiens · NCT06880094 · Data updated 2026-11-12
This will test whether optical genome mapping on a blood sample can find structural genetic changes in people with syndromic, complex, or familial orofacial clefts who do not yet have a genetic diagnosis.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are people with syndromic, complex, or familial orofacial clefts who have no established genetic diagnosis and who are followed at the Amiens-Picardie University Hospital.
✕Probably not a fit
People who already have a confirmed genetic diagnosis of their cleft, those who are pregnant or breastfeeding, under legal guardianship or without health insurance are excluded and would not benefit from participation.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
The study uses optical genome mapping (OGM), a high-resolution long-read method, alongside existing genetic information to search for structural variants (SVs) and copy-number variants (CNVs) that may explain congenital orofacial clefts. Participants provide a blood sample for OGM, which can directly visualize long labeled DNA molecules across the genome. This approach aims to detect variants that are missed by standard cytogenetics and short-read next-generation sequencing (NGS). Patients are recruited from the Amiens-Picardie University Hospital and must meet the study's inclusion and exclusion criteria.
Why it matters
Potential benefit: If successful, the method could provide a genetic diagnosis for some patients, improving genetic counseling and clinical decision-making.
How similar studies have gone: OGM has shown promise in other constitutional and cancer genetics for detecting SVs missed by cytogenetics and short-read NGS, but its targeted application to orofacial clefts is relatively new.
