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 ...
2,4 Dienoyl-CoA reductase, but also lysine degradation are performed by NADP-dependent oxidoreductases explaining how NADK2 deficiency can lead to multiple enzyme defects. [2] 2,4-Dienoyl-CoA reductase deficiency was initially described in 1990 based on a single case of a black female who presented with persistent hypotonia.
Aromatase deficiency is a rare condition characterized by extremely low levels or complete absence of the enzyme aromatase activity in the body. [2] It is an autosomal recessive disease resulting from various mutations of gene CYP19 (P450arom) which can lead to ambiguous genitalia and delayed puberty in females, continued linear growth into adulthood and osteoporosis in males and virilization ...
Many patients with 6-phosphogluconate dehydrogenase deficiency are carriers and have no symptoms. It has been discovered that symptoms manifest more frequently in female carriers. Depending on how severe the deficiency is, it has been demonstrated that enzyme activity is reduced by 35–65%. [citation needed]
Fabry disease is an inherited lysosomal storage disorder that is caused by a deficiency of alpha-galactosidase A. This enzyme deficiency is a result of an accumulation of glycosphingolipids found in the lysosomes and most cell types and tissues, which leads it to be considered a multisystem disease.
The inability to break down these molecules results in a wide variety of symptoms caused by damage to several different organ systems, including but not limited to the nervous system, skeletal system, eyes, and heart. The underlying mechanism is a deficiency of alpha-L iduronidase, an enzyme responsible for breaking down GAGs.
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]
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 ...
