CGL1 (medical condition)

A rare genetic disorder characterized by early-onset diabetes mellitus, loss of body fat, serious insulin resistance, high blood triglycerides and fatty liver. Type 1 is distinguished from type 2 by the origin of the genetic defect. Type 1 is caused by a defect on the AGPAT2 gene on chromosome 9q34.3. Type 1 seems to be less severe with some cases of type 2 resulting in premature death which can occur as early as the first year of life. Type 2 also involves mental retardation which is not seen in type 1. See also Berardinelli-Seip congenital lipodystrophy, type 1
