Waardenburg syndrome is a group of genetic conditions that can cause hearing loss and changes in coloring (pigmentation) of the hair, skin, and eyes. The four known types of Waardenburg syndrome are distinguished by their physical characteristics and sometimes by their genetic cause.
Waardenburg syndrome type 1 and type 2 have very similar features, although people with type 1 almost always have eyes that appear widely spaced and people with type 2 do not. In addition, hearing loss occurs more often in people with type 2 than in those with type 1. Waardenburg syndrome type 3 (sometimes called Klein-Waardenburg syndrome) includes abnormalities of the upper limbs in addition to hearing loss and changes in pigmentation. Waardenburg syndrome type 4 (also known as 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.
