Diagnostic Considerations

Diagnostic considerations based on the presenting symptom or sign can arise. For patients with developmental delays and intellectual disability, a general workup for chromosomal anomalies should be considered. For growth failure, endocrine, metabolic, and gastrointestinal consultations should be sought. Intracranial calcifications require an investigation into congenital TORCH (toxoplasmosis, other [syphilis, varicella-zoster, parvovirus B19], rubella, cytomegalovirus, herpes) infections.

Overall, however, the presence of Cockayne syndrome can usually be surmised based on the degree of neurologic dysfunction, the degree of growth failure, and the existence of eye anomalies such as cataracts.
