Multiple sulfatase deficiency (MSD), also known as Austin disease, [1] or mucosulfatidosis, [1] is a very rare autosomal recessive [2] lysosomal storage disease [3] caused by a deficiency in multiple sulfatase enzymes, or in formylglycine-generating enzyme, which activates sulfatases. [4]: 502 [5] It is similar to mucopolysaccharidosis. [6]
Exocrine pancreatic insufficiency (EPI) is the inability to properly digest food due to a lack or reduction of digestive enzymes made by the pancreas.EPI can occur in humans and is prevalent in many conditions [1] such as cystic fibrosis, [2] Shwachman–Diamond syndrome, [3] different types of pancreatitis, [4] multiple types of diabetes mellitus (Type 1 and Type 2 diabetes), [5] advanced ...
Inborn errors of metabolism are often referred to as congenital metabolic diseases or inherited metabolic disorders. [2] Another term used to describe these disorders is "enzymopathies". This term was created following the study of biodynamic enzymology , a science based on the study of the enzymes and their products.
Most individuals with G6PD deficiency are asymptomatic.When it induces hemolysis, it is usually is short-lived. [5]Most people who develop symptoms are male, due to the X-linked pattern of inheritance, but female carriers can be affected due to unfavorable lyonization or skewed X-inactivation, where random inactivation of an X-chromosome in certain cells creates a population of G6PD-deficient ...
Inherited metabolic disorders are one cause of metabolic disorders, and occur when a defective gene causes an enzyme deficiency. [6] These diseases, of which there are many subtypes, are known as inborn errors of metabolism. [7] Metabolic diseases can also occur when the liver or pancreas do not function properly. [3]
Lysosomal storage disorders are caused by lysosomal dysfunction usually as a consequence of deficiency of a single enzyme required for the metabolism of lipids, glycoproteins (sugar-containing proteins), or mucopolysaccharides. Individually, lysosomal storage diseases occur with incidences of less than 1:100,000; however, as a group, the ...
The disease was formerly known as myoadenylate deaminase deficiency (MADD). In virtually all cases, the deficiency has been caused by an SNP mutation, known as rs17602729 or C34T . While it was initially regarded as a recessive (or purely homozygous ) disorder, some researchers have reported the existence of similarly deleterious effects from ...
Sly syndrome, also called mucopolysaccharidosis type VII (MPS-VII), is an autosomal recessive lysosomal storage disease caused by a deficiency of the enzyme β-glucuronidase. This enzyme is responsible for breaking down large sugar molecules called glycosaminoglycans (AKA GAGs, or mucopolysaccharides). The inability to break down GAGs leads to ...
