Tyrosinemia is a rare genetic disorder that affects the body's ability to break down the amino acid tyrosine. This condition is caused by a deficiency in specific enzymes, leading to the accumulation of toxic substances in the body. Symptoms can include liver dysfunction, kidney problems, and neurological issues, which may vary in severity depending on the type of tyrosinemia. There are three main types of tyrosinemia: Type I, Type II, and Type III. Type I is the most severe and can lead to serious complications if not treated early. Treatment often involves a special diet low in tyrosine and phenylalanine, along with medications to manage symptoms and prevent complications.
