D008661 [edit on Wikidata] Inborn errors of metabolism form a large class of genetic diseases involving congenital disorders of metabolism. The majority are due to defects of single genes that code for enzymes that facilitate conversion types of inborn errors of metabolism of various substances (substrates) into others (products). In most of the disorders, problems inborn errors of metabolism symptoms arise due to accumulation of substances which are toxic or interfere with normal function, or to the effects of reduced inborn errors of amino acid metabolism ability to synthesize essential compounds. Inborn errors of metabolism are now often referred to as congenital metabolic diseases or inherited metabolic diseases. The term inborn error of metabolism was coined by a British inborn errors of metabolism made easy physician, Archibald Garrod (1857–1936), in 1908. He is known for work that prefigured the "one gene-one enzyme" hypothesis, based on his studies on the nature and inheritance of alkaptonuria. His seminal text, Inborn Errors of Metabolism was published in 1923.[1] Contents 1 Classification 2 Signs and symptoms 3 Diagnosis 4 Treatment 5 Epidemiology 6 References 7 External links Classification[edit] Traditionally the inherited metabolic diseases were classified

as disorders of carbohydrate metabolism, amino acid metabolism, organic acid metabolism, or lysosomal storage diseases. In recent decades, hundreds of new inherited disorders of metabolism have been discovered and the categories have proliferated. Following are some of the major classes of congenital metabolic diseases, with prominent examples of each class. Many others do not fall into these categories. Disorders of carbohydrate metabolism E.g., glycogen storage disease Disorders of amino acid metabolism E.g., phenylketonuria, maple syrup urine disease, glutaric acidemia type 1 Urea Cycle Disorder or Urea Cycle Defects E.g., Carbamoyl phosphate synthetase I deficiency Disorders of organic acid metabolism (organic acidurias) E.g., alcaptonuria, 2-hydroxyglutaric acidurias Disorders of fatty acid oxidation and mitochondrial metabolism E.g., Medium-chain acyl-coenzyme A dehydrogenase deficiency (often shortened to MCADD.) Disorders of porphyrin metabolism E.g., acute intermittent porphyria Disorders of purine or pyrimidine metabolism E.g., Lesch-Nyhan syndrome Disorders of steroid metabolism E.g., lipoid congenital adrenal hyperplasia, congenital adrenal hyperplasia Disorders of mitochondrial function E.g., Kearns-Sayre syndrome Disorders of peroxisomal function E.g., Zellweger syndrome Lysosomal storage disorders E.g., Gaucher's disease E.g., Niemann Pick disease Signs and symptoms[edit] Because of the enormous number of these diseases and wide range of systems affected, nearly every "presentin

are caused by an inherited genetic defect inborn errors of metabolism screening tests and that alter the body’s ability to derive energy from nutrients. The inborn errors of protein metabolism term inborn error of metabolism was introduced in 1908 by British physician Sir Archibald Garrod, who postulated that inherited disorders https://en.wikipedia.org/wiki/Inborn_error_of_metabolism such as alkaptonuria and albinism result from reduced activity or complete absence of enzymes involved in certain biochemical pathways. Garrod’s identification and categorization of inborn errors of metabolism represented an important conceptual advance in 20th-century medical genetics.The overall estimated incidence https://www.britannica.com/science/inborn-error-of-metabolism of inborn errors of metabolism is approximately 1 in every 4,000 live births.
