Lipodystrophy syndromes are a group of genetic or acquired disorders in which the body is unable to produce and maintain healthy fat tissue. [ 1 ] [ 2 ] The medical condition is characterized by abnormal or degenerative conditions of the body's adipose tissue .
Acquired generalized lipodystrophy (AGL), also known as Lawrence syndrome [1] and Lawrence–Seip syndrome, [1] is a rare skin condition that appears during childhood or adolescence, characterized by fat loss affecting large areas of the body, particularly the face, arms, and legs.
In most of the disorders, problems arise due to accumulation of substances which are toxic or interfere with normal function, or due to the effects of reduced ability to synthesize essential compounds. Inborn errors of metabolism are often referred to as congenital metabolic diseases or inherited metabolic disorders. [2]
The most common side effects include injection site reactions, hypersensitivity reactions (such as difficulty breathing, nausea, dizziness and fever), lipodystrophy (a loss of fat tissue resulting in an indentation in the skin or a thickening of fat tissue resulting in a lump under the skin) at the injection site, and ectopic calcifications of ...
Congenital generalized lipodystrophy (also known as Berardinelli–Seip lipodystrophy) is an extremely rare autosomal recessive condition, characterized by an extreme scarcity of fat in the subcutaneous tissues. [2] It is a type of lipodystrophy disorder where the magnitude of fat loss determines the severity of metabolic complications. [3]
Marfanoid–progeroid–lipodystrophy syndrome (MPL), also referred to as Marfan lipodystrophy syndrome (MFLS), is a variant of MFS in which Marfan symptoms are accompanied by features usually associated with neonatal progeroid syndrome (also referred to as Wiedemann–Rautenstrauch syndrome) in which the levels of white adipose tissue are ...
Metreleptin, sold under the brand name Myalept among others, is a synthetic analog of the hormone leptin used to treat various forms of dyslipidemia.It has been approved in Japan for metabolic disorders including lipodystrophy and in the United States as replacement therapy to treat the complications of leptin deficiency, in addition to diet, in patients with congenital generalized or acquired ...
Each type of leukodystrophy has a unique pathophysiology, but all five of these in some way affect a subset of glial cells, therefore disrupting myelin production and maintenance, and usually involve a mutation involving genes that code for enzymes necessary for the catabolism of very long chain fatty acids (VLCFAs) that are toxic to the myelin ...
