A Rare case in Indians -- Berardinelli–Seip Congenital Lipodystrophy
Berardinelli–Seip Congenital Lipodystrophy( BSCL) also called Congenital Generalised Lipodystrophy (CGL) is a very rare autosomal recessive metabolic syndrome with a prevalence of less than1 case in 12 million. About 200 cases have been reported so far world-wide. BSCL2 ,the more severe form of the disease with onset in the neonatal period or early infancy is present in Lebanon, Portugal, Norwa...
متن کاملGenotype-phenotype relationships in Berardinelli-Seip congenital lipodystrophy.
Generalised lipodystrophy of the Berardinelli-Seip type (BSCL) is a rare autosomal recessive human disorder with severe adverse metabolic consequences. A gene on chromosome 9 (BSCL1) has recently been identified, predominantly in African-American families. More recently, mutations in a previously undescribed gene of unknown function (BSCL2) on chromosome 11, termed seipin, have been found to be...
متن کاملPhenotypes of the N88S Berardinelli-Seip congenital lipodystrophy 2 mutation.
Recently, two missense mutations (N88S, S90L) in the Berardinelli-Seip congenital lipodystrophy gene have been identified in autosomal dominant distal hereditary motor neuropathy and Silver syndrome. We report the phenotypic consequences of the N88S mutation in 90 patients of 1 large Austrian family and two unrelated German families. Variation in the clinical and electrophysiological phenotype ...
متن کاملBrown adipose tissue function is accompanied by cerebral activation in lean but not in obese humans.
Brown adipose tissue (BAT) is able to generate heat and dissipate energy in response to cold exposure in mammals. It has recently been acknowledged that adult humans also have functional BAT, whose metabolic activity is reduced in obesity. In healthy humans, the cerebral mechanisms that putatively control BAT function are unclear. By using positron emission tomography (PET), we showed that cold...
متن کاملMfn2 is critical for brown adipose tissue thermogenic function
Mitochondrial fusion and fission events, collectively known as mitochondrial dynamics, act as quality control mechanisms to ensure mitochondrial function and fine-tune cellular bioenergetics. Defective mitofusin 2 (Mfn2) expression and enhanced mitochondrial fission in skeletal muscle are hallmarks of insulin-resistant states. Interestingly, Mfn2 is highly expressed in brown adipose tissue (BAT...
