1. Distrofia muscular de cinturas em crianças brasileiras: caracterização clínica, histologia e molecular
Limb-girdle muscular dystrophies (LGMD) are a heterogeneous group of genetic muscular dystrophies, involving 16 autosomal recessive subtypes and eight autosomal dominant subtypes. Autosomal recessive dystrophy is far more common than autosomal dominant dystrophy, particularly in children. The clinical course in this group is characterized by progressive prox

2. Phenotypic and immunohistochemical characterization of sarcoglycanopathies
INTRODUCTION: Limb-girdle muscular dystrophy presents with heterogeneous clinical and molecular features. The primary characteristic of this disorder is proximal muscular weakness with variable age of onset, speed of progression, and intensity of symptoms. Sarcoglycanopathies, which are a subgroup of the limb-girdle muscular dystrophies, are caused by mutati

3. Distrofias musculares progressivas de cinturas tipo 2: perfil epidemiolÃgico no estado do Cearà / Muscular Dystrophies progressive of waists type 2: profile epidemiologist in the state of CearÃ, Northeast of Brazil
Objective: To report the clinical and muscle biopsy findings from the recessive forms of limb girdle muscular dystrophies (LGMD type 2) seen in the state of CearÃ, Northeast of Brazil. Design: Case series. Setting: Tertiary care clinic, University hospital. Patients and Methods: We studied 41 patients from 32 families with chronic progressive weakness in a

4. Genetic epidemiology of muscular dystrophies resulting from sarcoglycan gene mutations.
BACKGROUND: The autosomal recessive limb-girdle muscular dystrophies (LGMDs) are a group of genetically heterogeneous muscle diseases characterised by progressive proximal limb muscle weakness. Six different loci have been mapped and pathogenetic mutations in the genes encoding the sarcoglycan complex components (alpha-, beta-, gamma-, and delta-sarcoglycan)

5. A first missense mutation in the delta sarcoglycan gene associated with a severe phenotype and frequency of limb-girdle muscular dystrophy type 2F (LGMD2F) in Brazilian sarcoglycanopathies.
Among the heterogeneous group of autosomal recessive limb-girdle muscular dystrophies (AR LGMDs), the sarcoglycanopathies (LGMD2C-2F) represent a subgroup characterised by defects in the gamma, alpha, beta, and delta sarcoglycan genes, respectively. Genotype-phenotype correlations in these forms of AR LGMD are important to enhance our understanding of protei

6. Mutational diversity and hot spots in the alpha-sarcoglycan gene in autosomal recessive muscular dystrophy (LGMD2D).
Sarcoglycanopathies are a genetically heterogeneous group of autosomal recessive muscular dystrophies in which the primary defect may reside in any of the genes coding for the different partners of the sarcolemmal sarcoglycan (SG) complex: the alpha-SG (LGMD2D at 17q21.2), the beta-SG (LGMD2E at 4q12), the gamma-SG (LGMD2C at 13q12), and the delta-SG (LGMD2F
