What is the treatment for Waardenburg syndrome? As Waardenburg syndrome is a genetic disease there is no curative treatment. Genetic counselling may be helpful for affected patients who want to start a family. [dermnetnz.org]
Treatment may include the use of hearing aids and/or cosmetic products or treatments (if desired) for skin hypopigmentation.[1] Waardenburg syndrome type 2 can be further divided into subtypes based on the genetic cause, when the responsible gene can [rarediseases.info.nih.gov]
Prognosis
Waardenburg syndrome type 3 prognosis Due to the very few number of cases described so far, information on prognosis and quality of life is limited. [healthjade.com]
Prognosis WS is a chronic condition. Life expectancy in children with Waardenburg syndrome is normal. [statpearls.com]
Etiology
[…] binding protein (e.g., Sin3A) as a co-repressor interacting with UBE2D3 (directly represses the promoter of the UBE2D3 gene) association of SNAI2 with CCND1 levels via UBE2D3 is important in the understanding of the complex role played by SNAI2 in the etiology [genatlas.medecine.univ-paris5.fr]
Genetic counseling is necessary.[4] Etiology WS is an autosomal dominant disorder. [statpearls.com]
Epidemiology
Type 4 WS is due to mutations in the genes for one of its receptors, EDNRB or endothelin-3, which is autosomal recessive and a very rare variant.[6] Epidemiology The prevalence is variable around the world. [statpearls.com]
Pathophysiology
Pathophysiology WS is a genetic disorder with autosomal dominant inheritance.[5] There are various hypotheses proposed about the pathogenesis and to explain the different types and clinical features. [statpearls.com]
Prevention
Dietary Changes: They are advised to prevent the complication of constipation and to maintain regular bowel movements. Conclusion: Although it is a genetic condition, the average lifespan of the child will be normal. [icliniq.com]
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. [healthjade.com]
