Acid lipase disease or deficiency is a name used to describe two related disorders of fatty acid metabolism. Acid lipase disease occurs when the enzyme lysosomal acid lipase that is needed to break down certain fats that are normally digested by the body is lacking or missing. This results in the toxic buildup of these fats in the body's cells ...
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]
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 ...
Pyruvate kinase deficiency is an inherited metabolic disorder of the enzyme pyruvate kinase which affects the survival of red blood cells. [ 4 ] [ 5 ] Both autosomal dominant and recessive inheritance have been observed with the disorder; classically, and more commonly, the inheritance is autosomal recessive .
Caused by the deficient enzyme N-acetylgalactosamine 4-sulfatase, Maroteaux-Lamy syndrome has a variable spectrum of severe symptoms. Neurological complications include clouded corneas, deafness, thickening of the dura (the membrane that surrounds and protects the brain and spinal cord), and pain caused by compressed or traumatized nerves and ...
Autosomal dominant GTP cyclohydrolase I deficiency; Other names: Autosomal dominant Segawa syndrome (the autosomal recessive form of Segawa syndrome is caused by mutations in a different gene that encodes tyrosine hydroxylase), Dopa-responsive dystonia 5a, Autosomal dominant DYT/PARK-GCH1 (designation in accordance with the Nomenclature of Genetic Movement Disorders maintained by the ...
It is caused by an accumulation of glycogen in the lysosome due to a deficiency of the lysosomal acid alpha-glucosidase enzyme (GAA). The inability to break down glycogen within the lysosomes of cells leads to progressive muscle weakness throughout the body and affects various body tissues, particularly in the heart , skeletal muscles , liver ...
Inborn errors of metabolism form a large class of genetic diseases involving congenital disorders of enzyme activities. [1] The majority are due to defects of single genes that code for enzymes that facilitate conversion of various substances into others . In most of the disorders, problems arise due to accumulation of substances which are ...
