Carbamoyl phosphate synthetase I deficiency has an autosomal recessive pattern of inheritance.. CPS I deficiency is inherited in an autosomal recessive manner. [1] This means the defective gene responsible for the disorder is located on an autosome, and two copies of the defective gene (one inherited from each parent) are required in order to be born with the disorder.
Symptoms of OAT deficiency are progressive, and between the ages of 45 and 65, most affected individuals are almost completely blind. [ 3 ] In some cases, affected individuals will present in the neonatal period with disease that closely mimics a classic urea cycle defect, such as ornithine transcarbamylase deficiency , as the block in ...

Aromatic L-amino acid decarboxylase deficiency has an autosomal recessive pattern of inheritance. Aromatic L-amino acid decarboxylase deficiency is an autosomal recessive condition, meaning an individual needs to have two faulty copies of the DDC gene in order to be affected. Usually, one copy is inherited from each parent. [3]
Traditionally the inherited metabolic diseases were classified as disorders of carbohydrate metabolism, amino acid metabolism, organic acid metabolism, or lysosomal storage diseases. [4] In recent decades, hundreds of new inherited disorders of metabolism have been discovered and the categories have proliferated.
As a result of TAT deficiency, the substrate tyrosine accumulates, causing ophthalmologic and dermatologic abnormalities. [3] Type III tyrosinemia results from a mutation in the HPD gene, which encodes the enzyme 4-hydroxyphenylpyruvate dioxygenase. [4] Type III tyrosinemia is the rarest of the three conditions, with only a few cases ever ...
Beta-ketothiolase deficiency is a rare, autosomal recessive metabolic disorder in which the body cannot properly process the amino acid isoleucine or the products of lipid breakdown. [ 1 ] [ 2 ] Along with SCOT deficiency , it belongs to a group of disorders called ketone utilisation disorders.
Most of the organic acidemias result from defective autosomal genes for various enzymes important to amino acid metabolism.Neurological and physiological harm is caused by this impaired ability to synthesize a key enzyme required to break down a specific amino acid, or group of amino acids, resulting in acidemia and toxicity to specific organs systems.
