Waardenburg syndrome

waardenburg syndrome Abstract auditory-pigmentary syndromes are caused by physical absence of melanocytes from the skin, hair, eyes, or the stria vascularis of the cochlea.

Waardenburg syndrome: a genetic disorder that causes deafness, white forelock (a frontal white blaze of hair), a difference of color between the iris of one eye and the other (heterochromia iridis), white eye lashes, and wide-set inner corners of the eyes the deafness is typically congenital. Waardenburg syndrome (ws) is diagnosed through the following procedures: clinical assessment of the physical features ws can be diagnosed through the presence of the clinical features. Waardenburg syndrome (ws) is named after the dutch ophthalmologist petrus johannes waardenburg, who, in 1947, first described a patient with hearing loss, dystopia canthorum (ie, lateral displacement of the inner canthi of the eyes), and retinal pigmentary differences in 1951, after identifying other patients with similar symptoms, waardenbu.

Waardenburg syndrome is a rare genetic disorder most often characterized by varying degrees of deafness, minor defects in structures arising from the neural crest, and pigmentation changes it was first described in 1951 the syndrome was later found to have four types for example, type ii was identified in 1971, to describe cases where dystopia canthorum was not present some types are now split into subtypes, based upon the gene responsible for the condition. The type of waardenburg syndrome you have depends on which gene or genes are mutated for example, types 1 and 3 are triggered by a mutation of the pax 3 gene on chromosome band 2q35 the mutation of any gene responsible for waardenburg syndrome affects melanocytes these are a type of skin cell.

What is waardenburg syndrome first discovered in 1948, waardenburg syndrome is a rare autosomal dominant condition characterized by craniofacial or interocular anomalies (facial and head structure deformities), bilateral deafness (deafness in both ears), and hypopigmentation of the skin, eyes and hair. Waardenburg syndrome (ws) is named after the dutch ophthalmologist petrus johannes waardenburg, who, in 1947, first described a patient with hearing loss, dystopia canthorum (ie, lateral displacement of the inner canthi of the eyes), and retinal pigmentary differences.

Waardenburg syndrome is a group of genetic conditions that can cause hearing loss and changes in coloring (pigmentation) of the hair, skin, and eyes although most people with waardenburg syndrome have normal hearing, moderate to profound hearing loss can occur in one or both ears.

Waardenburg syndrome is a genetic disorder that may be evident at birth (congenital) the range and severity of associated symptoms and findings may vary greatly from case to case however, primary features often include distinctive facial abnormalities unusually diminished coloration (pigmentation) of the hair, the skin, and/or the iris of both eyes (irides) and/or congenital deafness. Waardenburg syndrome has also been associated with a variety of other congenital disorders, such as intestinal and spinal defects, elevation of the scapula and cleft lip and palate sometimes this is concurrent with hirschsprung disease. Waardenburg syndrome is a rare genetic condition that affects the color of a person’s skin, hair, and eyes it can also cause hearing loss there are four main types of waardenburg syndrome.

Waardenburg syndrome is a group of conditions passed down through families the syndrome involves deafness and pale skin, hair, and eye color. A look at waardenburg syndrome, a group of diseases that cause changes in the body and eye color find out about how rare it is and the diagnosis.
