Sensorineural deafness can be present in 50 percent of the cases, presenting at birth or later in life, but mental deficiency is not seen. The clinical picture of this syndrome is very typical. [escholarship.org]

There have only been a total of 50 cases reported in total as of 2016.[1] Presentation[edit] The blue irises seen in the image present a common phenotype seen by patient of Type 4A Waardenburg Syndrome. [en.wikipedia.org]

If hypopigmentation affects more than half the body, depigmentation treatments may help. These treatments bleach all of your skin. They can make lighter patches less obvious. [healthline.com]
You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments. [rarediseases.info.nih.gov]
Standard Therapies Treatment The treatment of WS is directed toward the specific symptoms that are apparent in each individual. [rarediseases.org]
What is the treatment for Waardenburg syndrome? There is no direct treatment for Waardenburg syndrome itself, and as it is a genetic condition there is no cure. Genetic counselling may be beneficial for affected patients who want to start a family. [dermnetnz.org]
Etiology
Genetic counseling must be provided for families with this disorder, and the occurrence rate depends on the specific molecular etiology. References 1. [escholarship.org]
The parents of our patient were counseled in detail about the etiology and symptoms of WS. The child was referred to a specialist for hearing aid and speech therapy. [cureus.com]
Prevention
These may include the use of specially tinted glasses or contact lenses (e.g., to help reduce possible sensitivity to light), measures to help prevent or treat infection, or other preventive or therapeutic steps. [rarediseases.org]
Hearing aids can be employed for hearing deficits and can further help prevent speech and cognitive deficits. Melanin in healthy individuals protects against ultraviolet (UV) damage. [cureus.com]
