Untreated children may have repeated, often unrecognized, neurologic crises lasting one to seven days that can include change in mental status, abdominal pain, peripheral neuropathy, and/or respiratory failure requiring mechanical ventilation. Death in the untreated child usually occurs before age ten years, typically from liver failure, neurologic crisis, or hepatocellular carcinoma. Combined treatment with nitisinone and a low-tyrosine diet has resulted in a greater than 90% survival rate, normal growth, improved liver function, prevention of cirrhosis, correction of renal tubular acidosis, and improvement in secondary rickets." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />Hereditary tyrosinemia type I (TYRSN1) is an autosomal recessive disorder caused by deficiency of fumarylacetoacetase (FAH), the last enzyme of tyrosine degradation. The disorder is characterized by progressive liver disease and a secondary renal tubular dysfunction leading to hypophosphatemic rickets. Onset varies from infancy to adolescence. In the most acute form patients present with severe liver failure within weeks after birth, whereas rickets may be the major symptom in chronic tyrosinemia. Untreated, patients die from cirrhosis or hepatocellular carcinoma at a young age (summary by Bliksrud et al., 2005).&#13;
Genetic Heterogeneity of Hereditary Tyrosinemia&#13;
Tyrosinemia type II (TYRSN2; 276600), also known as Richner-Hanhart syndrome, is caused by mutation in the TAT gene (613018) on chromosome 16q22. Tyrosinemia type III (TYRNS3; 276710) is caused by mutation in the HPD gene (609695) on chromosome 12q24.  <a target="_blank" href="http://www.omim.org/entry/276700">http://www.omim.org/entry/276700</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />Tyrosinemia type III is the rarest of the three types. The characteristic features of this type include intellectual disabilities, seizures, and periodic loss of balance and coordination (intermittent ataxia). Liver problems do not occur in types II and III.<br /><br />Tyrosinemia type II often begins in early childhood and affects the eyes, skin, and mental development. Signs and symptoms include eye pain and redness, excessive tearing, abnormal sensitivity to light (photophobia), and thick, painful skin on the palms of the hands and soles of the feet (palmoplantar hyperkeratosis). About half of individuals with tyrosinemia type II have some degree of intellectual disability.<br /><br />About 1 in 10 of all newborns have temporarily elevated levels of tyrosine (transient tyrosinemia). These cases are not genetic. The most likely causes are vitamin C deficiency or an immature liver due to premature birth.<br /><br />In addition, tyrosinemia type I can lead to liver and kidney failure, softening and weakening of the bones (rickets), and an increased risk of liver cancer (hepatocellular carcinoma). Some affected children have repeated neurologic crises that consist of changes in their mental state, reduced sensation in the arms and legs (peripheral neuropathy), abdominal pain, and serious breathing problems (respiratory failure). These crises can last from 1 to 7 days. Without treatment, children with tyrosinemia type I often do not survive past the age of 10. With early diagnosis and treatment, though, affected individuals can live into adulthood.<br /><br />There are three types of tyrosinemia, distinguished by their symptoms and genetic cause. Tyrosinemia type I is the most severe form of this disorder and usually begins in the first few months of life. Affected infants do not gain weight and grow at the expected rate (failure to thrive) because eating high-protein foods leads to diarrhea and vomiting. Affected infants may also have yellowing of the skin and whites of the eyes (jaundice), a cabbage-like odor, and an increased tendency to bleed (particularly nosebleeds). <br /><br />Tyrosinemia is a genetic disorder characterized by problems breaking down the amino acid tyrosine, which is a building block of most proteins. If the condition is untreated, tyrosine and its byproducts build up in tissues and organs, which can lead to serious health problems.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/tyrosinemia">https://medlineplus.gov/genetics/condition/tyrosinemia</a></div></div>

<div class="spaceAbove">Metabolic acidosis (MA) is characterized by a fall in blood pH due to a reduction of serum bicarbonate concentration. This can occur as a result of either the accumulation of acids (high anion gap MA) or the loss of bicarbonate from the gastrointestinal tract or the kidney (hyperchloremic MA). By definition, MA is not due to a respirary cause.</div>
