Mutations in the skeletal muscle ryanodine receptor (RYR1) gene have been associated with a wide range of phenotypes including the malignant hyperthermia (MH) susceptibility trait, Central Core Disease (CCD) and other congenital myopathies characterized by early onset and predominant proximal weakness. We report a patient presenting at 77 years with a(More)
The skeletal muscle ryanodine receptor plays a crucial role in excitation-contraction (EC) coupling and is implicated in various congenital myopathies. The periodic paralyses are a heterogeneous, dominantly inherited group of conditions mainly associated with mutations in the SCN4A and the CACNA1S genes. The interaction between RyR1 and DHPR proteins(More)
OBJECTIVES To establish the consistency of the previously reported pattern of muscle involvement in a large cohort of patients with molecularly defined ryanodine receptor type 1 (RYR1)-related myopathies, to identify possible additional patterns, and to compare magnetic resonance imaging (MRI) findings with clinical and genetic findings. DESIGN Blinded(More)
King-Denborough syndrome (KDS), first described in 1973, is a rare condition characterised by the triad of dysmorphic features, myopathy, and malignant hyperthermia susceptibility (MHS). Autosomal dominant inheritance with variable expressivity has been reported in several cases. Mutations in the skeletal muscle ryanodine receptor (RYR1) gene have been(More)
Dynamin 2 (DNM2)-related dominant centronuclear myopathy is usually a mild disorder, but more severe variants have been associated with mutations affecting the pleckstrin homology (PH) domain of the protein, mainly implicated in different forms of Charcot-Marie-Tooth Disease (CMT). Whilst DNM2-related CMT may feature non-neurological findings including(More)
BACKGROUND Congenital myopathies are inherited primary disorders of the muscle caused by mutations affecting structural, contractile, or regulatory proteins. In the more than 20 genes associated to these conditions, ryanodine receptor type 1 gene (RYR1) is responsible for the most common forms and is associated with a wide range of clinical phenotypes and(More)
