Abstract
Lipodystrophies are a heterogeneous group of diseases affecting adipose tissue distribution. Familial partial lipodystrophy of the Dunnigantype (FPLD) is a rare autosomal, dominant disorder caused by missense mutations in lamin A/C (LMNA) gene where selectiveloss of subcutaneous adipose tissue from the limbs and trunk, and accumulation of fat in the neck and face, is usually associated witha variety of metabolic disorders including insulin resistance, diabetes mellitus, dyslipidemia, hepatic steatosis and high blood pressure.In this report we present clinical and molecular features of three Polish women with FLPD phenotype coming from one family (a motherand her two daughters). FPLD was recognised under the circumstances of diabetes treatment, where sequencing of LMNA gene revealedheterozygous R482W mutation. In order to be able to recognise monogenic diabetes associated with lipodystrophy, it is important to bevery precise in physical examination while diagnosing diabetes and to be aware of the necessity of performing genetic testing. Diabetesappropriatedifferential diagnosis is essential for the treatment strategy, anticipation of the disease progression, and determination of theprognosis. It is necessary for an individual mutation carrier to look carefully at the patient’s family.
