Waardenburg Syndrome Precision Panel

Overview

• Waardenburg Syndrome (WS) is a genetic disorder characterized by the association of pigmentation abnormalities, including depigmented patches of the skin and hair, blue eyes (heterochromia irides), and sensorineural hearing loss. It also presents with other clinical features involving musculoskeletal abnormalities, gastrointestinal malformations and neurological defects. WS is considered a defect in the melanocyte and neural crest development, where a complex interconnecting regulatory network of genes work in synergism for an appropriate development of melanocytes. It is typically inherited in an autosomal dominant pattern.  
• The Igenomix Waardenburg Syndrome Precision Panel can be used to make an accurate and directed diagnosis as well as a differential diagnosis of hearing loss ultimately leading to a better management and prognosis of the disease. It provides a comprehensive analysis of the genes involved in this disease using next-generation sequencing (NGS) to fully understand the spectrum of relevant genes involved.  

Indication

• The Igenomix Waardenburg Syndrome Precision Panel is indicated for those patients with a clinical suspicion or diagnosis with or without the following manifestations: 
  • Cleft lip 
  • Constipation 
  • Deafness 
  • Extremely pale blue eyes or nonmatching eye colors
  • Pale color skin, hair and eyes 
  • Decreased intellectual function 

Clinical Utility

The clinical utility of this panel is: 

• The genetic and molecular confirmation for an accurate clinical diagnosis of a symptomatic patient.  
• Early initiation of treatment with a multidisciplinary team in the form of hearing aids and cochlear implants, social services and speech therapy.
• Risk assessment and genetic counselling of asymptomatic family members according to the mode of inheritance. 
• Improvement of delineation of genotype-phenotype correlation. 
• Unravel important developmental pathways in the neural crest and derivatives that could potentially lead to Waardenburg Syndrome.
