ADAM17 is an 824-amino acid polypeptide.[5] [6]ADAM17 has multidomain structure that includes a pro-domain, a metallo-protease domain, a disintegrin domain, a cysteine-rich domain, an EGF-like domain, a transmembrane domain, and a cytoplasmic tail.
A novel experimental approach to the hereditary haemochromatosis treatment is the maintenance therapy with polymeric chelators. [ 69 ] [ 70 ] [ 71 ] These polymers or particles have a negligible or null systemic biological availability and they are designed to form stable complexes with Fe 2+ and Fe 3+ in the GIT and thus limiting the uptake of ...
Brunner syndrome is caused by a monoamine oxidase A (MAOA) deficiency, which leads to an excess of monoamines in the brain, such as serotonin, dopamine, and norepinephrine (noradrenaline). In both mice and humans, a mutation was located on the eighth exon of the MAO-A gene, which created a dysfunctional MAO-A gene.
Treatment is guided by the severity and specific cause of the disease. Treatment focuses on eliminating the underlying problem, whether that means discontinuing drugs suspected to cause it or treating underlying sepsis. Diagnosis and treatment of serious thrombocytopenia is usually directed by a hematologist.
Niemann–Pick disease (NP), also known as acid sphingomyelinase deficiency, is a group of rare genetic diseases of varying severity.These are inherited metabolic disorders in which sphingomyelin accumulates in lysosomes in cells of many organs.
Methylenetetrahydrofolate reductase deficiency is the most common genetic cause of elevated serum levels of homocysteine (hyperhomocysteinemia). It is caused by genetic defects in MTHFR, which is an important enzyme in the methyl cycle. [1] Common variants of MTHFR deficiency are asymptomatic and have only minor effects on disease risk. [2]
This leads to a multiple vitamin deficiency, affecting the fat-soluble vitamin A, vitamin D, vitamin E, and vitamin K. [11] However, many of the observed effects are due to vitamin E deficiency in particular. [11] Acanthocytosis in a patient with abetalipoproteinemia. Signs and symptoms vary and present differently from person to person.
This enzyme is responsible for the interconversion of mannose-6-phosphate and mannose-1-phosphate, and its deficiency leads to a shortage in GDP-mannose and dolichol (Dol)-mannose (Man), two donors required for the synthesis of the lipid-linked oligosaccharide precursor of N-linked glycosylation.
