27-Hydroxylase Deficiency

Rattus norvegicus
Sterol 27-hydroxylase is a mitochondrial cytochrome P-450 species (CYP27) that catalyzes the first step in the degradation of steroid side chain in cholesterol to produce bile acids in the liver. When there are low concentrations of 27-Hydroxylase, patients will exhibit cerebrotendinous xanthomatosis, an autosomal recessive disorder characterized by the accumulation of cholestanol and cholesterol due to the inability to break down the lipids. The formation of xanthomas (deposits of lipids) in the nervous system and tendons will cause symptoms such as dementia, ataxia, and cataracts. Other symptoms may include damaged liver cells and body tissues.

3-beta-Hydroxysteroid Dehydrogenase Deficiency

Rattus norvegicus
3-beta-hydroxysteroid dehydrogenase (HSD) deficiency is an extremely rare inborn error of metabolism (IEM) and autosomal recessive disorder of the steroidogenesis pathway. It is caused by an defect in the HSD3B2 gene which encodes for the 3 beta-hydroxysteroid dehydrogenase enzyme, which is responsible for forming cortisol from 11b,17a,21-trihydroxypregnenolone. When the enzyme is not correctly produced, cortisol levels in the cell are lowered, and as cortisol is used in the production of other steroids, it may affect their levels as well. 3-beta-HSD deficiency is characterized by low levels of cortisol produced in the adrenal glands. Symptoms include abnormal genitalia for both males and females, as well as infertility. There is also a more severe salt-wasting form of this deficiency, characterized by dehydration. Treatment for 3-beta-HSD deficiency includes steroid replacement, as well as sex hormone replacement during puberty to allow proper development. Surgery can also be used to correct any genital abnormalities that may occur. It is estimated that 3-beta-HSD deficiency affects less than 1 in 1,000,000 individuals, with around 60 cases reported.

3-Hydroxy-3-methylglutaryl-CoA Lyase Deficiency

Rattus norvegicus
3-Hydroxy-3-methylglutaryl-CoA lyase deficiency (3-Hydroxy-3-methylglutaric acidemia; Leucine metabolism, defect in, HMG-CoA lyase deficiency) is an autosomal recessive disease caused by a mutation in the HMGCL gene which codes for hydroxymethylglutaryl-CoA lyase. A deficiency in this enzyme results in accumulation of 3-hydroxymethylglutaric acid, 3-hydroxyisovaleric acid, 3-methylcrotonylglycine and 3-methylglutaconic acid (cis and trans form), and methylglutaric acid in urine; and ammonia in blood. Symptoms include cardiomyopathy, dehydration, hypotonia, lactic acidosis, and pancreatitis. Treatment includes a low-fat, low-protein, high-carbohydrate diet.
