Although most people with Waardenburg syndrome have normal hearing, moderate to profound hearing loss can occur in one or both ears. The hearing loss is present from birth (congenital). People with this condition often have very pale blue eyes or different colored eyes, such as one blue eye and one brown eye. Sometimes one eye has segments of two different colors. Distinctive hair coloring (such as a patch of white hair or hair that prematurely turns gray) is another common sign of the condition.  The features of Waardenburg syndrome vary among affected individuals, even among people in the same family. There are four recognized types of Waardenburg syndrome, which are distinguished by their physical characteristics and sometimes by their genetic cause. Types I and II have very similar features, although people with type I almost always have eyes that appear widely spaced and people with type II do not. In addition, hearing loss occurs more often in people with type II than in those with type I. Type III (sometimes called Klein-Waardenburg syndrome) includes abnormalities of the arms and hands in addition to hearing loss and changes in pigmentation. Type IV (also known as Waardenburg-Hirschsprung disease or Waardenburg-Shah syndrome) has signs and symptoms of both Waardenburg syndrome and Hirschsprung disease, an intestinal disorder that causes severe constipation or blockage of the intestine.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":"50,000","Age_at_Onset_Snippet_Text__c":"as a Newborn and as an Infant","SourceID__c":"ORPHA:3440","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Grouping","MONDO_ID__c":"MONDO:0018094","ORPHANET_ID__c":"ORPHA:3440","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Síndrome de waardenburg","Spanish_Description_Source__c":"ORPHA:3440","Spanish_Description__c":"El síndrome de Waardenburg (SW) es un trastorno que se caracteriza por grados variables de sordera y defectos menores en estructuras derivadas de la cresta neural que resultan en anomalías en la pigmentación de los ojos, cabello y piel.
