The extent of fat loss determines the severity of associated metabolic complications such as diabetes mellitus, hypertriglyceridemia, hepatic steatosis, and acanthosis nigricans.Four loci have been identified for the autosomal recessive congenital generalized lipodystrophy (CGL), namely, (1) AGPAT2, (2) BSCL2, (3) CAV1, and (4) PTRF.Four loci have been identified for autosomal dominant familial partial lipodystrophy (FPL), namely, (1) LMNA, (2) PPARG, (3) AKT2, and (4) PLIN1.CIDEC is the locus for autosomal recessive FPL, and LMNA and ZMPSTE24 are loci for autosomal recessive mandibuloacral dysplasia-associated lipodystrophy.Molecular basis of many rare forms of genetic lipodystrophies remains to be elucidated.The most prevalent variety of lipodystrophy develops after prolonged duration of protease inhibitor containing highly active antiretroviral therapy in HIV-infected patients.The acquired generalized lipodystrophy and acquired partial lipodystrophy are mainly autoimmune in origin.Localized lipodystrophies occur due to drug or vaccine injections, pressure, panniculitis, and other unknown reasons.The current management includes cosmetic surgery and early identification and treatment of metabolic and other complications.
