Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include individuals with congenital conditions affecting eye movement or cranial nerve function.
✕Probably not a fit
Patients with cranial nerve disorders linked to known genetic mutations or acquired conditions like trauma or stroke may not benefit from this study.

What this trial studies
This observational study aims to identify genetic factors associated with congenital cranial dysinnervation disorders (CCDDs) and strabismus, which can lead to misalignment of the eyes. The Engle Lab has a decade-long focus on the genetics of eye movement and eyelid disorders, expanding their research to include individuals with additional anomalies linked to these conditions. Participants may include those with and without eye movement defects, allowing for a broader understanding of the genetic spectrum of these disorders.
Why it matters
Potential benefit: If successful, this study could lead to improved diagnosis and treatment options for patients with strabismus and related congenital disorders.
How similar studies have gone: Previous studies have shown success in identifying genetic factors in similar conditions, suggesting a promising avenue for this research.

Show full inclusion / exclusion criteria
Inclusion Criteria: * The Engle Lab is very interested in enrolling individuals with congenital conditions related to eye movement, cranial nerve and brainstem-based dysfunction, often broadly referred to as congenital cranial dysinnervation disorders (CCDDs). Exclusion Criteria: * Individuals with cranial nerve disorders associated with known disorders, such as Saethre-Chotzen associated with established genetic mutations, or acquired conditions including trauma, stroke, tumor or spinal cord injuries.
