My wife has complete heterochromia. Her left eye is brown and right eye is blue. Also, she is deaf in her left ear. I think she is suffering from Waardenburg syndrome. However, no one in her family is suffering from this syndrome. I think she has Waardenburg type 2 because she doesn't have other symptoms. Can you please tell me what are the chances that our baby can suffer from this syndrome and what precautions we can take? See answer
