Berardinelli-Seip syndrome and progressive myoclonus epilepsy.

Epileptic Disord 2019 Feb;21(1):117-121

Child Neurology and Psychiatry Unit, "Regina Montis Regalis" Hospital, Mondovì.

Berardinelli-Seip syndrome, or congenital generalized lipodystrophy type 2 (CGL2), is characterized by a lack of subcutaneous adipose tissue and precocious metabolic syndrome with insulin resistance, resulting in diabetes, dyslipidaemia, hepatic steatosis, cardiomyopathy, and acanthosis nigricans. Most reported mutations are associated with mild, non-progressive neurological impairment. We describe the clinical and EEG data of a patient with progressive myoclonus epilepsy (PME), CGL2, and progressive neurological impairment, carrying a homozygous BSCL2 nonsense mutation. Read More

Acquired generalised lipodystrophy and type 1 diabetes mellitus in a child: a rare and implacable association.

BMJ Case Rep 2018 Aug 3;2018. Epub 2018 Aug 3.

Department of Paediatrics, Post Graduate Institude of Medical Education and Research, Chandigarh, India.

Lipodystrophy syndromes are frequently associated with marked degree of insulin resistance and lipoatrophic diabetes. Although acquired generalised lipodystrophy (AGL) has been known to be associated with various autoimmune disorders, type 1 diabetes mellitus (T1DM) is very rarely reported to occur with AGL. Combination of AGL and T1DM can lead to a totally different phenotype with very difficult-to-treat diabetes and progressive complications of both the conditions. Read More

Division of Nutrition and Metabolic Diseases, Department of Internal Medicine and the Center for Human Nutrition, UT Southwestern Medical Center, Dallas, Texas.

Despite considerable progress in identifying causal genes for lipodystrophy syndromes, the molecular basis of some peculiar adipose tissue disorders remains obscure. In an Israeli-Arab pedigree with a novel autosomal recessive, multiple symmetric lipomatosis (MSL), partial lipodystrophy and myopathy, we conducted exome sequencing of two affected siblings to identify the disease-causing mutation. The 41-year-old female proband and her 36-year-old brother reported marked accumulation of subcutaneous fat in the face, neck, axillae, and trunk but loss of subcutaneous fat from the lower extremities and progressive distal symmetric myopathy during adulthood.

Section on Integrative Physiology and Metabolism, Joslin Diabetes Center and Department of Medicine, Harvard Medical School, Boston, MA

Ectopic lipid accumulation in the liver is an almost universal feature of human and rodent models of generalized lipodystrophy and is also a common feature of type 2 diabetes, obesity, and metabolic syndrome. Here we explore the progression of fatty liver disease using a mouse model of lipodystrophy created by a fat-specific knockout of the insulin receptor (F-IRKO) or both IR and insulin-like growth factor 1 receptor (F-IR/IGFRKO). These mice develop severe lipodystrophy, diabetes, hyperlipidemia, and fatty liver disease within the first weeks of life. Read More

Department of Bioinformatics and Molecular Neuropathology, Meiji Pharmaceutical University.

Nasu-Hakola disease (NHD) is a rare intractable autosomal recessive disorder, characterized by pathological bone fractures and progressive dementia owing to multifocal bone cysts and leukoencephalopathy, caused by various genetic mutations of either DAP12 or TREM2. Loss-of-function of TREM2-DAP12, constituting a signaling complex on osteoclasts and microglia, plays a central role in the pathogenesis of NHD. Recently, NHD has been recognized as the disease entity designated "microgliopathy". Read More

Department of Endocrinology, Diabetes and Metabolism, Centro Hospitalar São João, Alameda Prof. Hernâni Monteiro, 4200, Porto, Portugal.

Background: Human lipodystrophies are uncommon disorders, with important clinical consequences, which are often undiagnosed. The Barraquer-Simons syndrome is a form of partial symmetric lipodystrophy of unknown etiology, characterized by the loss of subcutaneous adipose tissue, limited to upper part of the body. Insulin resistance and metabolic complications are less common than with other lipodystrophy subtypes. Read More

Fitting the pieces of the puzzle together: a case report of the Dunnigan-type of familial partial lipodystrophy in the adolescent girl.

BMC Pediatr 2016 Mar 14;16:38. Epub 2016 Mar 14.

MEDGEN Medical Center, Orzycka 27, 02-695, Warsaw, Poland.

Background: Familial partial lipodystrophy of the Dunnigan type (FPLD 2) is a rare autosomal dominant disorder caused by the mutations of the lamin A/C gene leading to the defective adipogenesis, premature death of adipocytes and lipotoxicity. FPLD 2 is characterized by a progressive loss of subcutaneous adipose tissue in the limbs and trunk, and accumulation of body fat in the face and neck with accompanying severe metabolic derangements including insulin resistance, glucose intolerance, diabetes, dyslipidemia, steatohepatitis. Clinical presentation of FPLD 2 can often lead to misdiagnosis with metabolic syndrome, type 2 diabetes or Cushing syndrome. Read More

Additive loss-of-function proteasome subunit mutations in CANDLE/PRAAS patients promote type I IFN production.

J Clin Invest 2015 Nov 20;125(11):4196-211. Epub 2015 Oct 20.

Autosomal recessive mutations in proteasome subunit β 8 (PSMB8), which encodes the inducible proteasome subunit β5i, cause the immune-dysregulatory disease chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE), which is classified as a proteasome-associated autoinflammatory syndrome (PRAAS). Here, we identified 8 mutations in 4 proteasome genes, PSMA3 (encodes α7), PSMB4 (encodes β7), PSMB9 (encodes β1i), and proteasome maturation protein (POMP), that have not been previously associated with disease and 1 mutation in PSMB8 that has not been previously reported. One patient was compound heterozygous for PSMB4 mutations, 6 patients from 4 families were heterozygous for a missense mutation in 1 inducible proteasome subunit and a mutation in a constitutive proteasome subunit, and 1 patient was heterozygous for a POMP mutation, thus establishing a digenic and autosomal dominant inheritance pattern of PRAAS.

TREM2 mRNA Expression in Leukocytes Is Increased in Alzheimer's Disease and Schizophrenia.

PLoS One 2015 2;10(9):e0136835. Epub 2015 Sep 2.

Department of Neuropsychiatry, Molecules and Function, Ehime University Graduate School of Medicine, Toon, Ehime, Japan.

Unlabelled: TREM2 and TYROBP are causal genes for Nasu-Hakola disease (NHD), a rare autosomal recessive disease characterized by bone lesions and early-onset progressive dementia. TREM2 forms a receptor signaling complex with TYROBP, which triggers the activation of immune responses in macrophages and dendritic cells, and the functional polymorphism of TREM2 is reported to be associated with neurodegenerative disorders such as Alzheimer's disease (AD). The objective of this study was to reveal the involvement of TYROBP and TREM2 in the pathophysiology of AD and schizophrenia. Read More

Deletion of serine/arginine-rich splicing factor 3 in hepatocytes predisposes to hepatocellular carcinoma in mice.

Hepatology 2015 Jan 25;61(1):171-83. Epub 2014 Nov 25.

Medical Research Service, VA San Diego Healthcare System, San Diego, CA; Department of Medicine, Division of Endocrinology and Metabolism, University of California San Diego, La Jolla, CA.

Unlabelled: Alterations in RNA splicing are associated with cancer, but it is not clear whether they result from malignant transformation or have a causative role. We show here that hepatocyte-specific deletion of serine/arginine-rich splicing factor 3 (SRSF3) impairs hepatocyte maturation and metabolism in early adult life, and mice develop spontaneous hepatocellular carcinoma (HCC) with aging. Tumor development is preceded by chronic liver disease with progressive steatosis and fibrosis. Read More

The natural history of HIV-associated lipodystrophy in the changing scenario of HIV infection.

HIV Med 2014 Nov 21;15(10):587-94. Epub 2014 Apr 21.

Infectious Diseases Clinics, Policlinico University Hospital, Modena, Italy.

Objectives: In long-term HIV-infected patients, peripheral lipoatrophy (LA) and central lipohypertrophy (LH) appear to be related to the same insults (virus and antiretroviral drugs), but are likely to be associated with different fat depot physiologies. The objective of this study was to describe the natural history of lipodystrophy assessed using dual energy X-ray absorptiometry (DEXA) and computed tomography (CT) in a large HIV out-patients metabolic clinic.

Methods: An observational retrospective study was carried out including HIV-infected patients recruited at the Metabolic Clinic of Modena, Modena, Italy, who were assessed for lipodystrophy and had at least two anthropometric evaluations using DEXA for leg fat per cent mass and abdominal CT for visceral adipose tissue (VAT).

Adipose-specific knockout of SEIPIN/BSCL2 results in progressive lipodystrophy.

Diabetes 2014 Jul 12;63(7):2320-31. Epub 2014 Mar 12.

School of Biotechnology and Biomolecular Sciences, the University of New South Wales, Sydney, NSW, Australia

Berardinelli-Seip congenital lipodystrophy type 2 (BSCL2) is the most severe form of human lipodystrophy, characterized by an almost complete loss of adipose tissue and severe insulin resistance. BSCL2 is caused by loss-of-function mutations in the BSCL2/SEIPIN gene, which is upregulated during adipogenesis and abundantly expressed in the adipose tissue. The physiological function of SEIPIN in mature adipocytes, however, remains to be elucidated. Read More
