Liraglutide use in pediatric type 2 familial partial lipodystrophy caused by LMNA mutation: a case report
Abstract
Background: Type 2 familial partial lipodystrophy (FPLD2), or Dunnigan syndrome, is a rare genetic disorder characterized by selective subcutaneous fat loss, metabolic complications, and insulin resistance due to LMNA gene mutations. This case report describes the clinical presentation and treatment of a Chinese family with FPLD2, highlighting liraglutide's role in glycemic and lipid control.
Case presentation: The index patient is a 14-year-old girl, presenting with fat accumulation in the neck, loss of subcutaneous fat on the face, arms, legs, and trunk, and metabolic complications including diabetes mellitus with insulin resistance, hepatomegaly, and dyslipidemia. The diagnosis of FPLD2 was confirmed by the identification of a heterozygous mutation c.1456 A > G (p. Lys486Glu) in exon 8 of the LMNA gene. The patient was initially treated with a diabetic diet, metformin, and insulin therapy, but glycemic control was only achieved after introducing liraglutide, resulting in satisfactory control within two months. The variable manifestations of FPLD2 within the family (the proband, her father, and elder sister), all carrying the same LMNA mutation are presented, highlighting the complexity of this genetic disorder. The fast clinical response to liraglutide in our patient suggests a potential therapeutic role for Glucagon-like peptide-1 receptor agonists in the management of metabolic complications in FPLD2.
Conclusions: This case report underscores the importance of…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
