OBJECTIVES: Familial partial lipodystrophy type 2 is the most well-known subtype of lipodystrophy. We describe for the first time the phenotype of a case with lipodystrophy, who carried heterozygous mutation c.G1394A (p.G465D) in the LMNA gene.
CASE PRESENTATION: A 17-year-old girl was diagnosed with FPLD2 due to severe loss of subcutaneous fat in the extremities, buttocks and metabolic complications. However, there was no accumulation of fat over her face and neck, which is remarkably different from the FPLD2 clinical phenotypes. Two years of surveillance showed the challenge due to unable control of insulin resistance, glucose and lipid metabolism. Whole exome sequencing revealed the heterozygous mutation c.1394G>A at exon 11 of LMNA gene (p.G465D).
CONCLUSIONS: Our case displayed an atypical phenotype of FPLD2 with metabolic anomalies, not cardiovascular diseases. The difficulties of medical management in this case pointed out the urgent need for more effective treatment for individuals suffering from this rare disease.
