Dr. Amira Mobarak, Michelle Sebastiano (Clinical Secretary) Children with Wilson disease cannot get rid of extra copper they receive from their diet but do not need. Our program is also strongly committed to offering participation in clinical trials for innovative therapies. This can lead to low blood sugar, muscle weakness and heart problems. In enzyme replacement therapy (ERT), we give your child the enzyme they need through an intravenous (IV) line. Examples are medium-chain acyl-coenzyme A dehydrogenase (MCAD) deficiency and very long–chain acyl-coenzyme A dehydrogenase (VLCAD) deficiency. Medicines and special diets can treat many of these disorders. OXPHOS; VARS2; cardioencephalomyopathy; mitochondrial disorders. © 2018 The Authors.

Keywords: In collaboration with the nutritional research unit at BC Children’s Hospital Research Institute (Dr. Rajavel Elango) we are creating a research pipeline including in vivo stable isotope testing for the development of innovative nutritional therapies for children with disorders such as PKU, pyridoxine dependent epilepsy and cerebral creatine deficiencies. You may be offered a telehealth (virtual) appointment. The biochemical phenotype comprised a combined Complex I and Complex IV OXPHOS defect in muscle, with patient fibroblasts displaying normal OXPHOS activity. HHS Most children’s bodies filter out this extra copper. REXO2 is an oligoribonuclease active in human mitochondria. These disorders affect how the body makes energy. Metabolic Brain Disease, 32(1)267–270. Medicines and special diets can treat many of these disorders. 2019 Nov;124(4):273-277. doi: 10.1080/03009734.2019.1670297. The Division of Biochemical Diseases actively participates in the Canadian Inherited Metabolic Diseases Research Network (CIMDRN). These are the following: VON GIERKE’S (TYPE I GSD) CIMDRN provides the evidence needed to improve outcomes and health care services for children with inborn errors of metabolism (IEM). Another name for this area of genetics is metabolic genetics. Here we provide a detailed genetic, clinical, and biochemical description of 13 patients, from nine unrelated families, harboring VARS2 mutations. This helps them to do the best physically and mentally and have the best possible quality of life. Children with these disorders cannot use fats for energy. PI TIDE-BC, Gabriella Horvath, MD, PhD, FRCPC, FAAP, FCCMG We work closely with other doctors in the clinic and hospital if your child gets sick. Mitochondrial myopathies and encephalomyopathies. Families will have an opportunity to contribute information about their experiences with care for IEM and their own well-being. These are problems with how the body makes, breaks down or uses proteins, fats or carbohydrates. This site needs JavaScript to work properly. The protocol includes 3 tiers, starting from community based screening to specialized diagnostic assessment to next generation sequencing. 1999 Oct;29(10):886-98. doi: 10.1046/j.1365-2362.1999.00540.x. VARS2 and TARS2 mutations in patients with mitochondrial encephalomyopathies. These sections are called lysosomes. Perez M, Jaundoo R, Hilton K, Del Alamo A, Gemayel K, Klimas NG, Craddock TJA, Nathanson L. Front Pediatr. Diagnosing and treating metabolic diseases early can improve a child’s quality of life. Adult Metabolic Consultant at VGH, Ramona Salvarinova, MD, MSci, FCCMG, FRCPC Gloria Ho (Research Assistant) This disease is due to the deficiency of keto-acid (branched-chain) dehydrogenase. May Al Malki, (Saudi Arabia) start date: July 1, 2016 – ongoing. Our program is part of the American Board of Medical Genetics–certified training program at the University of Washington. Learn about paying for care at Seattle Children’s, including insurance coverage, billing and financial assistance. This process is called infusion. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. They are important to all bodily functions.). (2012). A : Micro‐oxygraphy performed in P4 and control fibroblasts cultured in…, Scheme and molecular model of VARS2 protein. Neurometabolic clinic: in close collaboration with the division of neurology and community neurologists. IEM are a group of rare genetic diseases that affect metabolic pathways and can lead to a variety of clinical symptoms. Begliuomini C, Magli G, Di Rocco M, Santorelli FM, Cassandrini D, Nesti C, Deodato F, Diodato D, Casellato S, Simula DM, Dessì V, Eusebi A, Carta A, Sotgiu S. BMC Med Genet. Children with these disorders cannot use protein properly for energy. Examples of urea cycle disorders are ornithine transcarbamylase (OTC) deficiency, argininosuccinic aciduria and citrullinemia. Clipboard, Search History, and several other advanced features are temporarily unavailable. Many children born with metabolic diseases need care and treatment throughout their lives.

Division of Biochemical Diseases This causes sugars and proteins to build up in the body. As co-investigators in CIMDRN (Canadian Inherited Metabolic Disease Research Network) we are contributing with our clinical data to a national observational database, which will help to create practice informed evidence for treatments of conditions diagnosed by expanded newborn screening. 2001 Aug;32(4):183-90. doi: 10.1055/s-2001-17372.
