Köbberling-Dunnigan syndrome, also known as partial familial lipodystrophy, is a rare genetic disorder characterized by abnormal distribution of adipose tissues. Many people with Köbberling-Dunnigan syndrome develop insulin resistance, a condition in which body tissues cannot adequately respond to insulin hormone. Insulin is a hormone that helps regulate the level of your blood glucose. Köbberling-Dunnigan syndrome can be due to mutations in several different genes. However, type 2 Köbberling-Dunnigan syndrome is caused by the mutation of the LMNA gene, which is located on the long arm of chromosome 1 as 1q22.
