This condition was first described by a Dutch ophthalmologist and a geneticist, Dr.Petrus Johannes Waardenburg, in the year 1951. Hence the syndrome is named after him. In his findings, he observed that during the development of the embryo, there were disturbances to the melanocytes that resulted in patchy areas of depigmentation. What Is Meant By ...
It is a rare genetic condition and is diagnosed soon after birth.It affects about one in 42000 cases across the world and one in 2,12,000 cases in the Netherlands (the only country that has low penetration in the world).It has got neither racial nor gender predilection. It affects any population and any age group.Type III is very rare, and 19 % of reported cases are type IV.There are four main types of which, types I and II, are commonly reported.Type III (Klein- Waardenburg syndrome) and type IV (Waardenburg Shah syndrome) are extremely rare.During the development of the embryo (embryogenesis), there are disturbances to the neural crest-derived melanocytes that result in areas of depigmentation that are seen in patches. This results in...Another main reason is due to the mutations seen in the genes. These gene mutations affect the neural crest cells.Type I and III are due to mutations in the PAX3 gene at chromosome 2q.Type II is further subdivided into 2A, 2B,2C, and 2D.The symptoms are usually seen soon after birth. These symptoms specifically alter the morphological appearance. They are associated with musculoskeletal defects and Hirschsprung syndrome. The symptoms vary in each type of Waardenburg syndrome. The most common symptoms are: 1. Pigmentation changes (the eyes are differently colored). 2. Auditory defe...
Type I:It is the most common type. 1. Sensorineural deafness(deafness caused due to damage to the inner structures of the ear). 2. Short philtrum, retro positioned maxilla (the upper jaw is displaced backward). 3. Morphological changes in the facial structure with broad nasal root and wide-set eyes. 4. Dystopia canthus (the medial corners of the ey...
The syndrome can be diagnosed soon after birth, or in some cases, they are diagnosed at least by early childhood. As the child grows, the morphological features may help to diagnose this condition. The clinician concludes the diagnosis from the clinical evaluation by looking at their physical appearance and by obtaining a proper history from their ...
As Waardenburg syndrome is a genetic disorder, there is no permanent cure for this disease. However, supportive treatment will provide symptomatic relief and improve the quality of life. 1. Cochlear Implant: An implantis a device that is inserted into the inner ear where the auditory nerve is stimulated and sends impulses to the brain. This is foll...
Jan 21, 2023 · Waardenburg Syndrome (WS) is a rare genetic disorder that affects the development of certain features, such as the eyes, ears, and pigmentation of the hair, skin, and eyes. There are four main types of WS, each caused by mutations in different genes. Type 1 is caused by mutations in the PAX3 gene, type 2 is caused by mutations in the MITF ...

Waardenburg Syndrome is characterized by a combination of distinctive features, such as widely spaced eyes (hypertelorism), a broad nasal bridge, a white forelock (a patch of white or gray hair near the forehead), and changes in pigmentation of the iris (heterochromia iridis) or the hair. These characteristics can vary greatly from person to ...
