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.
The term fatty acid oxidation disorder (FAOD) is sometimes used, especially when there is an emphasis on the oxidation of the fatty acid. [3]In addition to the fetal complications, they can also cause complications for the mother during pregnancy.
Diet composition and quantity, in particular omega-6 fatty acid and fructose, have important roles in disease progression from MASL to MASH and fibrosis. [35] [36] Choline deficiency can lead to the development of MASLD. [37] Higher consumption of processed, red, and organ meats have been associated with higher risk of developing MASLD.
Methylmalonic acidemia has an autosomal recessive pattern of inheritance.. Methylmalonic acidemias have an autosomal recessive inheritance pattern, which means the defective gene is located on an autosome, and two copies of the gene—one from each parent—must be inherited to be affected by the disorder.
[10] [11] [12] Mutations in the HADHA or HADHB genes that cause mitochondrial trifunctional protein deficiency disrupt all functions of this enzyme complex. [13] Without enough of this enzyme complex, long-chain fatty acids cannot be metabolized. As a result, these fatty acids are not converted to energy, which can lead to some features of this ...
Dyslipidemia is a metabolic disorder characterized by abnormally high or low amounts of any or all lipids (e.g. fats, triglycerides, cholesterol, phospholipids) or lipoproteins in the blood. [1]
Kidney failure is the major cause of morbidity and mortality in complete LCAT deficiency, while in partial deficiency (fish eye disease) major cause of morbidity is visual impairment due to corneal opacity. These patients have low HDL cholesterol but surprisingly premature atherosclerosis is not seen. However, there are some reported cases.
Elevated 3-hydroxyisovaleric acid is a clinical biomarker of biotin deficiency. Without biotin, leucine and isoleucine cannot be metabolized normally and results in elevated synthesis of isovaleric acid and consequently 3-hydroxyisovaleric acid, isovalerylglycine, and other isovaleric acid metabolites as well. Elevated serum 3-hydroxyisovaleric ...
