OBJECTIVE To report the genetic and metabolic profile of patients with Berardinelli-Seip syndrome (BSCL) followed at Instituto da Criança, HC-FMUSP. SUBJECTS AND METHODS Patients with clinical features of BSCL (n = 5), all female, were evaluated through serum levels of glucose, insulin, lipids, leptin, and liver enzymes. Abdominal sonography and DNA analysis were also performed. RESULTS Lep...
Leptin is essential for energy homeostasis and regulation of food intake. Patients with congenital generalized lipodystrophy (CGL) due to mutations in 1-acylglycerol-3-phosphate-O-acyltransferase 2 (AGPAT2) and the CGL murine model (Agpat2(-/-) mice) both have severe insulin resistance, diabetes mellitus, hepatic steatosis, and low plasma leptin levels. In this study, we show that continuous le...
Clinical and Mutational Features of Three Chinese Children with Congenital Generalized Lipodystrophy
OBJECTIVE To investigate the clinical and molecular features of congenital generalized lipodystrophy (CGL) in three Chinese patients with various typical manifestations. METHODS Data on clinical symptoms, results of laboratory analyses, and previous treatments in three Chinese patients were collected by a retrospective review of medical records. All coding regions and adjacent exon-intron jun...
Congenital generalized lipodystrophy (CGL) is a rare autosomal recessive disorder characterized by near complete absence of adipose tissue from birth. Recently, mutations in 1-acylglycerol-3-phosphate O-acyltransferase 2 (AGPAT2) and Berardinelli-Seip congenital lipodystrophy 2 (BSCL2) genes were reported in pedigrees linked to chromosomes 9q34 and 11q13, respectively. There are limited data re...
Background Congenital generalized lipodystrophies (CGL) or Berardinelli-Seip Congenital Lipodystrophy (BSCL) are rare autosomal recessive disorders with reduction of subcutaneous and visceral adipose tissue, associated with deregulation of lipidic and glycidic metabolism, most of them developing insulin resistance and diabetes mellitus during the second decade of life. There are four CGL syndro...
A several fold increase in triacylglycerol is observed in the livers of lipodystrophic Agpat2-/- mice. We have previously reported an unexpected increase in the phosphatidic acid (PA) levels in the livers of these mice and that a few specific molecular species of PA were able to transcriptionally upregulate hepatic gluconeogenesis. In the current study, we measured the metabolites and expressio...
A 3-year-old female patient presenting with an unknown syndrome of a neonatal progeroid appearance, lipodystrophy, pulmonary hypertension, cutis marmorata, feeding disorder and failure to thrive was investigated by whole-genome sequencing. This revealed a de novo, heterozygous, frame-shift mutation in the Caveolin1 gene (CAV1) (p.Phe160X). Mutations in CAV1, encoding the main component of the c...
