Individuals with Familial partial lipodystrophy (FPLD), Dunnigan variety is a rare autosomal dominant disorder caused by missense mutations in Lamin gene are predisposed to insulin resistance and its complications including features of polycystic ovarian syndrome. We present a single case report about a 26-year-old Chinese woman consulted for infertility. On physical examination acanthosis nigricans and central distribution of fat were found. Her masculine type morphology, muscular appearance of the limbs and excess fat deposits in the face and neck promote us to suspect the existence of partial lipodystrophy. Biochemistry testing confirmed glucose intolerance associated with a severe insulin resistance, hypertriglyceridemia, and polycystic ovary syndrome. The detection of a heterozygous missense mutation in LAMIN A/C gene at position 482 confirmed the diagnosis of FPLD2. In conclusion, characteristic features of FPLD and mutation screening allow early diagnosis of this disorder, and facilitate appropriate clinical treatment.
