The muscle protein Dok-7 is essential for activation of the receptor kinase MuSK, which governs NMJ formation, and DOK7 mutations underlie familial limb-girdle myasthenia (DOK7 myasthenia), a neuromuscular disease characterized by small NMJs. (ox.ac.uk)

Emery-Dreifuss muscular dystrophy can have several different patterns of inheritance. (medlineplus.gov)
Emery-Dreifuss dystrophy is a muscular dystrophy with multiple modes of inheritance. (msdmanuals.com)

Emery-Dreifuss muscular dystrophy is a condition that affects the joints, muscles, and heart. (nih.gov)

Many cases of muscular dystrophy represent new occurrences of disease, where there is no prior family history. (nih.gov)
The sex-linked forms (dystrophinopathies) include DMD, BMD, and Emery-Dreifuss MD. 8 In these X-linked forms of the disease, the defect leads to alterations in the genes coding for the protein dystrophin . (uspharmacist.com)
If a child is conceived with one of the germ cells carrying a mutation, the child can inherit a disease-causing gene flaw, even though blood DNA tests in the parents won't show any flaw. (mda.org)
FSHD was first distinguished as a disease in the 1870s and 1880s when French physicians Louis Théophile Joseph Landouzy and Joseph Jules Dejerine followed a family affected by it, thus the initial name Landouzy-Dejerine muscular dystrophy . (mdwiki.org)

Clinical relevance of atrial fibrillation/flutter, stroke, pacemaker implant, and heart failure in Emery-Dreifuss muscular dystrophy: a long-term longitudinal study. (medscape.com)
Centers are expected to provide an environment and core resources that will enhance collaborations of established basic, clinical, and behavioral science investigators to study muscular dystrophy research questions. (nih.gov)
In 1954 based on their own detailed clinical studies and an extensive review of the earlier literature, Walton and Nattrass 1 proposed a new and valuable classification of the muscular dystrophies. (bmj.com)
During the past 10 years the European Neuromuscular Centre, now based in the Netherlands, has encouraged and coordinated both clinical and laboratory studies of dystrophy, many of which have led directly or indirectly to the advances reported here. (bmj.com)
