rare genetic disorders in animals

Deoxyribonucleic acid (aka DNA) is the fundamental molecule lying in the base of the living world. There exist many animal models where naturally occurring disease-causing mutations that are homologous to mutations in the equivalent human disease have been discovered. Eur Spine J. Author information: (1)National Center for Advancing Translational Sciences, National Institutes of Health, Medical Center Drive, Bethesda, Maryland. By Mindy Cohan, VMD As a veterinarian, I have naturally contemplated my dogs’ genetic background and pondered about their inherent risk for breed-specific health problems. She has experience potty and house training as well as teaching dogs tricks such as sit and shake. It also has a database of animal models of human diseases, which occur naturally in New Zealand’s farm animal populations, and is planning a significant step forward in their genomics research initiatives through an active search for more large animal models. CS is a Research Fellow in the Developmental Genetics and Pathology Group in the Pathology Department at the University of Otago. www.nzirdr.org.nz/animal_models/our_models, http://www.nzirdr.org.nz/animal_models/our_models, http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/, https://doi.org/10.1186/s13023-015-0327-5.

Meckel syndrome (MKS) is a rare, lethal, genetic disorder characterized by occipital encephalocele, large polycystic kidneys, and polydactyly as well as associated abnormalities that may include cleft lip/palate, cardiac and genital anomalies, central nervous system (CNS) malformations, liver fibrosis, and bone dysplasia. Nat Rev Genet. She joined the pet genomics company Basepaws in 2017 after earning her Bachelor’s degree in Genetics. Maxmen A. Exome sequencing deciphers rare diseases. Accumulation of lysosome-derived storage bodies in neurons and in other cells types is a hallmark of this disease. The complexity and genetic heterogeneity of diseases such as PD have a huge impact on whether mouse genetic models successfully model the human disease. Some cat breeds have the higher genetic predisposition to these conditions. However, livestock models such as sheep may offer some advantages for developing new large animal models of genetic disease. Sheep are also more socially acceptable animal models for research as compared to dogs. Childers CP, Reese JT, Sundaram JP, Vile DC, Dickens CM, Childs KL, et al. The identification of genetic diseases is highly important for the betterment of their timely and accurate diagnosis and treatment. Heterozygous cats will remain unaffected. Nevertheless, orphan diseases cannot be ignored, as collectively they pose a heavy burden on society. This enzyme is in charge of modifying procollagen into collagen. 2009;18:244–53. J Rheumatol Suppl. It is not a substitute for professional care. The second genetic trait linked to the condition is an autosomal dominant mutation resulting in abnormal packaging of type I collagen.

In this disorder, some of the cells grow and some don't. Nat Rev Neurosci. The neuronal ceroid lipofuscinoses (NCL) are a group of recessively inherited lethal neurodegenerative diseases. Historically, pharmaceutical companies have chosen not to develop treatments for these diseases. Large animal models of rare genetic disorders: sheep as phenotypically relevant models of human genetic disease. Studying this condition in cats is not only important for the betterment of cat care and health, but it may also serve as a good model for the improvement of the human disease diagnosis and treatment 6. TSD is a genetically heterogeneous rare autosomal recessive neurodegenerative disease with aggregation of Gm2 ganglioside in the nerve cells of the central nervous system [49]. 2015. 1985;76:482–90.

Medically reviewed by Brian Levine, MD. 1997;7:336–42. Genetic Disorders in Children. Luhken G. Genetic testing for phenotype-causing variants in sheep and goats. These two different breeds of sheep have been further characterized, and the recessive PKD in affected newborn lambs were found to have phenotypic characteristics similar to MKS, with a shared genetic abnormality in the 2 flocks (manuscript in preparation). Hematologically important mutations: Gaucher disease. The sheep genome illuminates biology of the rumen and lipid metabolism. Most people generally don't understand the reason behind their unusual appearance and behavior. Tammen I, Houweling PJ, Frugier T, Mitchell NL, Kay GW, Cavanagh JA, et al. Sadie is passionate about canine well-being so she feeds her pup all-natural meals and no table scraps. Annu Rev Cell Dev Biol. The promise of neuroprotective agents in Parkinson's disease. 2011;43:12–26. Mol Ther. As it is recessive, it will only show in homozygous forms (organisms that carry two copies of the defective gene), while heterozygous forms (organisms with two different copies of the gene – one defective and one healthy) will remain unaffected. It affects around 1 in 70,000 newborns. Ablepharon-macrostomia syndrome. statement and A review in 2012, globally of sheep, cattle and goats, of traits for which causal gene variants were known [41] listed 14 autosomal recessive diseases analogous to diseases such as Batten disease, Ehlers-Danlos syndrome, inherited rickets and Gaucher disease. Rezapour M, Novara G, Meier PA, Holste J, Landgrebe S, Artibani W. A 3-month preclinical trial to assess the performance of a new TVT-like mesh (TVTx) in a sheep model. Feline myotonia congenita (MC) is a hereditary neuromuscular disorder affecting skeletal muscles in the domestic shorthair cats. Gaucher disease (GD) is a lysosomal storage disorder encompassing three main forms (types 1, 2 and 3), a fetal form and a variant with cardiac involvement (Gaucher disease - ophthalmoplegia - cardiovascular calcification or Gaucher-like disease).

If you have or suspect you may have a health problem, you should consult your health care provider. Furthermore, the sheep industry in New Zealand has pedigree information on millions of animals, including those that have genotype information. Indeed, ovine models of genetic disease such as the GD model have shown their worth as excellent pre-clinical models. In the following paragraphs we present several naturally existing sheep models of human disease. 2009;155:386–92. See more ideas about rare genetic disorders, genetic disorders, genetics. They are less expensive to purchase and manage than many closely related species such as cattle, particularly in New Zealand, which has a very large sheep population of approximately 30 million sheep. Primary glaucoma is often breed-specific, with Burmese and Siamese cats at highest risks from it. Polycystic kidney diseases (PKD) are the most common inherited kidney disorders, in which many cysts form in the kidneys and other organs. 2013;110:3507–12.

An ideal transgenic mouse model of human disease has a robust phenotype, well-defined abnormalities and pathological features that replicate the human disease well [11]. There is also no disruption of the functioning of leukocytes. Further investigations including biochemical and histopathological examinations showed that the affected neonatal lambs displayed severe clinical signs that were highly similar to the most severe and very rare form of this disease, GD type-2 [53]. Its main aims are to help people affected by rare diseases, to create awareness about rare diseases, promote improvements to health care and social supports, and facilitate research into rare diseases by networking with researchers, affected patients, clinicians and policy makers. MRC Laboratory for Molecular Cell Biology and London. 154 likes. 2011;39:1124–35. That is why today we chose ten such diseases in efforts to take them apart and reflect on their clinical significance. Accessed March 21, 2014. 2014;344:1168–73.
