The broad spectrum and heterogeneity of clinical presentation can delay diagnosis by decades for patients with this rare disease. Diagnosis can be confirmed with genetic testing of the CXCR4 gene.

- Recurrent warts unresponsive to treatment(e.g., skin, anogenital)
- Recurring respiratory tract infections(2 or more pneumonias within 1 year)
