A cohort analysis of familial partial lipodystrophy from two Mediterranean countries

Aim To assess the disease burden of familial partial lipodystrophy (FPLD) caused by LMNA (FPLD2) and PPARG (FPLD3) variants to augment the knowledge of these rare disorders characterized by selective fat loss and metabolic complications. Materials and Methods An observational longitudinal study, including 157 patients (FPLD2: 139 patients, mean age 46 ± 17 years, 70% women; FPLD3: 18 patients, mean age: 44 ± 17 years, 78% women) from 66 independent families in two countries (83 from Turkey and 74 from Spain), was conducted. Results Patients were diagnosed at a mean age of 39 ± 19 years, 20 ± 16 years after the first clinical signs appeared. Men reported symptoms later than women. Symptom onset was earlier in FPLD2. Fat loss was less prominent in FPLD3. In total, 92 subjects (59%) had diabetes (age at diagnosis: 34 ± 1 years). Retinopathy was more commonly detected in FPLD3 (P
