What is (are) 2-methyl-3-hydroxybutyric aciduria ?
2-methyl-3-hydroxybutyric aciduria is an inherited disorder in which the body cannot effectively process the amino acid isoleucine. Signs and symptoms of this condition usually develop in infancy or early childhood and include metabolic acidosis, hypoglycemia, hypotonia, seizures, movement problems, retinal degeneration, and hearing loss. Affected males have severe neurodegeneration with loss of developmental milestones, whereas females have mild to moderate developmental delay. 2-methyl-3-hydroxybutyric aciduria is caused by mutations in the HSD17B10 gene; it has an X-linked dominant pattern of inheritance.
