Secondary deficiencies are caused by a disease or disorder of the intestinal tract, and disappear when the disease is treated.
Primary enzyme deficiencies are typically caused by genetic mutations that affect the production or function of a specific enzyme in the body. These mutations can disrupt the normal metabolic processes that rely on the affected enzyme, leading to a deficiency in its activity and subsequent symptoms or health problems.
caused by a deficiency of the enzyme heparan sulfate sulfamidase, due to mutations in the SGSH gene on chromosome 17. Type IIIA is felt to be the most severe of the four types, in which symptoms appear and death occurs at an earlier age
Phenylketonuria (PKU) is caused by mutations in the PAH gene, which provides instructions for making an enzyme called phenylalanine hydroxylase. This enzyme is essential for the breakdown of the amino acid phenylalanine. Mutations in the PAH gene lead to a deficiency in this enzyme, resulting in a build-up of phenylalanine in the body.
A deficiency of the enzyme Beta hexosaminidase A leads to Tay-Sachs disease, a rare genetic disorder that results in the progressive destruction of nerve cells in the brain and spinal cord. Symptoms typically appear in infancy and include developmental delays, loss of motor skills, and eventually, blindness and seizures.
Without the alpha-galactosidase A enzyme, fatty compounds starts to line the blood vessels.
Primary enzyme deficiencies are typically caused by genetic mutations that affect the production or function of a specific enzyme in the body. These mutations can disrupt the normal metabolic processes that rely on the affected enzyme, leading to a deficiency in its activity and subsequent symptoms or health problems.
PKD is caused by a deficiency in the enzyme, pyruvate kinase.
Tay-Sachs disease (TSD) is a fatal condition caused by a deficiency of the enzyme hexosaminidase A (Hex-A).
Krabbe's disease is caused by a deficiency of the enzyme galactoside beta-galactosidase.
A primary nutritional deficiency is caused by a simple lack of the nutrient in the diet. For instance, cats that are fed strictly fish develop a primary taurine deficiency because the fish don't have enough taurine in them. A secondary nutritional deficiency is caused by another disease process limiting the amount of the nutrient available to the body. For instance, a cow may develop secondary B12 deficiency if it eats too much of certain weeds that have a vitamin B12-destroy enzyme.
The genetic defect causes a deficiency of the enzyme glucocerebrosidase that is responsible for breaking down a certain type of fat and releasing it from fat cells.
Tay-Sachs disease (TSD) is a fatal condition caused by a deficiency of the enzyme hexosaminidase A (Hex-A).
Acid phosphatase deficiency is primarily caused by genetic mutations that affect the production or function of the enzyme. It can also be acquired through certain medical conditions or drug use that impairs enzyme activity.
A nutrient deficiency caused by inadequate absorption is known as a malabsorption deficiency. This can occur when the body is unable to effectively absorb specific nutrients, such as vitamins or minerals, due to issues with digestion or absorption processes in the intestines. It can lead to various health complications if not adequately addressed.
Wolman's disease is caused by a genetic defect (with a recessive pattern of inheritance) that results in deficiency of an enzyme that breaks down cholesterol.
The severity of the symptoms depends on the extent of the enzyme deficiency, and range from a feeling of mild bloating to severe diarrhea.
Beriberi is caused by thiamine (vitamin B1) deficiency Goitre can be caused by iodine deficiency - although there are other potential causes. Scurvy is caused by vitamin C deficiency Night blindness (Nyctalopia) can have many different causes - but one cause is vitamin A deficiency.
