Genetic analysis of muscular dystrophies: our experience in Mexico.

Muscular dystrophies are a group of well-defined genetic disorders characterized by the variable distribution of muscle wasting and progressive weakness. The diagnosis and treatment of these diseases remain challenging due to genetic heterogeneity and clinical overlapping. Herein, we describe our 10 years' experience with the diagnosis and management of muscular dystrophy patients.

Structural and sequence variants in patients with Silver-Russell syndrome or similar features-Curation of a disease database.

Silver-Russell syndrome (SRS) is a clinically and molecularly heterogeneous disorder involving prenatal and postnatal growth retardation, and the term SRS-like is broadly used to describe individuals with clinical features resembling SRS. The main molecular subgroups are loss of methylation of the distal imprinting control region (H19/IGF2:IG-DMR) on 11p15.5 (50%) and maternal uniparental disomy of chromosome 7 (5%-10%).

Comparison of mutation profiles in the Duchenne muscular dystrophy gene among populations: implications for potential molecular therapies.

Novel therapeutic approaches are emerging to restore dystrophin function in Duchenne Muscular Dystrophy (DMD), a severe neuromuscular disease characterized by progressive muscle wasting and weakness. Some of the molecular therapies, such as exon skipping, stop codon read-through and internal ribosome entry site-mediated translation rely on the type and location of mutations. Hence, their potential applicability worldwide depends on mutation frequencies within populations.
