Metabolic Disorders: The Hidden Link to Cognitive Health
Introduction Ornithinemia is a rare and often misdiagnosed inherited metabolic disorder caused by a defect in the enzyme ornithine transcarbamylase (OTC). It is an X-linked disorder, meaning that it is passed along through the X chromosome from mother to son, and can affect both males and females. Symptoms can range from mild to severe and […]
LYSINURIA
Introduction to Lysinuria: Defining a Rare Metabolic Disorder Lysinuria, clinically designated as Lysinuric Protein Intolerance (LPI), is a complex, multisystemic, and exceptionally rare autosomal recessive metabolic disorder. At its physiological core, this condition is defined by a fundamental defect in the basolateral membrane transport of cationic amino acids, specifically lysine, arginine, and ornithine. This transport […]
NIEMANN-PICK DISEASE
Introduction and Definition Niemann-Pick Disease (NPD) represents a cluster of rare, inherited metabolic disorders characterized primarily by the inability of the body’s cellular machinery to properly process and store lipids, or fats. Classified as a lysosomal storage disorder, NPD results from specific enzyme deficiencies or defects in protein function that lead to the excessive accumulation […]
