Congenital generalized lipodystrophy (CGL) is a rare autosomal recessive disease characterized by near total absence of adipose tissue from birth. Several metabolic alterations in carbohydrate (diabetes mellitus) and lipid metabolism and involvement of heart, bone and ovaries are also observed in this disease. Patients typically have low serum levels of leptin and adiponectin. Several genes were studied to identify the molecular alteration responsible for CGL, which have been found to contribute to lipid droplet formation in adipocytes.
