Estudio intergeneracional de la mutación que causa la distrofia miotónica de tipo 1 en Costa Rica
Intergenerational study of the mutation that causes myotonic dystrophy type 1 in Costa Rica
(Revista de Neurología 2003; 36: 20-25, 2003-01-01)
Introduction. Myotonic dystrophy type 1 is a neuromuscular, degenerative and progressive disease, with an autosomal
dominant pattern of inheritance, variable eTressivity and incomplete penetrance. The genetic defect is ...
Clinical and molecular diagnosis of a Costa Rican family with autosomal recessive myotonia congenital (Becker disease) carrying a new mutation in the CLCN1 gene
(Revista de Biología Tropical 56(1) p.1-11, 2006-08-18)
Myotonia congenita is a muscular disease characterized by myotonia, hypertrophy, and stiffness. It
is inherited as either autosomal dominant or recessive known as Thomsen and Becker diseases, respectively.
Here we confirm ...
Diagnóstico molecular de la distrofia miotónica (DM) en Costa Rica
(Acta Medica Costarricense :43 (4) p. 159-167, 2001-10)
La Distrofia Miotónica es una enfermedad multisistémica de herencia autosómica dominante. El defecto molecular es una expansión del trinucleótido CTG presente en Ia región 3' no codificante (3' UTR) del gen DMPK, localizado ...
Aspectos genéticos y moleculares de la distrofia miotónica
Molecular and genetic aspects of myotonic dystrophy
(1999)
Mvotonic Dystrophy is a multisystemic illness which affects several tissues such as the muscle, the brain and some endocrine tissues. It presents a dominant of autosomic inheritance with incomplete penetrance and variable ...
Mutaciones inestables: causa de algunas enfermedades neurológicas hereditarias
(1999-06)
Las mutaciones inestables o amplificación de tripletas constituyen un tipo de alteración genética descubierto durante la última década. En condiciones normales, regiones específicas de algunos genes están constituidas por ...
Somatic instability of the expanded CTG triplet repeat in myotonic dystrophy type 1 is a heritable quantitative trait and modifier of disease severity
(Human Molecular Genetics, 2012 Vol. 21, No. 16. 3558–3567, 2012-05-30)
Deciphering the contribution of genetic instability in somatic cells is critical to our understanding of many
human disorders. Myotonic dystrophy type 1 (DM1) is one such disorder that is caused by the expansion
of a CTG ...
A polymorphism in the MSH3 mismatch repair gene is associated with the levels of somatic instability of the expanded CTG repeat in the blood DNA of myotonic dystrophy type 1 patients
(2016-04)
Somatic mosaicism of the expanded CTG repeat in myotonic dystrophy type 1 is age-dependent, tissuespecific and expansion-biased, contributing toward the tissue-specificity and progressive nature of the symptoms. Previously, ...
Disabilities caused by unstable mutations in Costa Rica
(Revista de Biología Tropical 52(3) p.501-505, 2004-12-15)
Myotonic dystrophy and fragile X syndrome are two genetically determined relatively common disabilities.
Both are examples of a new type of mutation mechanism called unstable or dynamic mutations, triple
repeats expansions ...
Enfermedad de Huntington infantil: reporte del primer caso en Costa Rica confirmado por análisis molecular
Infantile Huntington`s disease: first case in Costa Rica confirmed by molecular genetic analysis
(2016)
La enfermedad de Huntington (HD, por sus siglas
en inglés) es una enfermedad neurodegenerativa
progresiva, con una prevalencia en la población
caucásica de 10.6-13.7 casos por 100 000 habitantes.
La prevalencia de la ...
Aspectos genéticos y moleculares de las enfermedades miotónicas
Molecular and genetic aspects of the myotonic conditions
(Revista de Neurología 38 (7) p 668-674, 2004)
Aim. The aim is to review the molecular and genetic aspects of the dystrophic and no-dystrophic myotonias. Background.
Myotonic diseases are hereditary conditions of the skeletal muscle, classified in two groups depending ...
