Disorders of Tyrosine Metabolism T2 Rudolph's Pediatrics, 22e YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-149723-7 LK accesspediatrics.mhmedical.com/content.aspx?aid=6724599 RD 2024/03/28 AB The five known inherited disorders in the metabolism of the nonessential amino acid tyrosine are each very rare and present in different ways. Four of them share a degree of hypertyrosinemia, but this sign is not specific and can also be found in other conditions such as transient tyrosinemia of the preterm newborn, which results from delayed maturation of tyrosine-metabolizing enzymes; in scurvy; and in many forms of general liver disease.
