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 ...
Parental age effects, but no evidence for an intrauterine effect in the transmission of myotonic dystrophy type 1
(European Journal of Human Genetics p.1-8, 2014-07-23)
Myotonic dystrophy type 1 (DM1) is caused by the expansion of an unstable CTG repeat (g.17294_17296(45_1000)) with more repeats associated with increased disease severity and reduced age at onset. Expanded disease-associated ...
Identification and Functional Characterization of CLCN1 Mutations Found in Nondystrophic Myotonia Patients
Mutations in the gene coding for the skeletal muscle Cl− channel (CLCN1) lead to dominant or recessive myotonia. Here, we identified and characterized CLCN1 mutations in Costa Rican patients, who had been clinically diagnosed ...
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 ...
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 ...
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 ...
