GNE myopathy (previous names: HIBM, DMRV, IBM2) is a unique distal myopathy with quadriceps sparing. This recessively inherited myopathy has been diagnosed in various regions of the world with more than 150 disease-causing mutations already identified. Several of those are proven or suspected to be founder mutations in certain regional clusters and are described in this review. The review also ...

Hereditary inclusion body myopathy (hIBM) is an adult-onset hereditary myopathy, usually with distal onset and quadriceps sparing. This myopathy is autosomal recessive and associated to UPD-N-acetylglucosamine-2-epimerase/N-acetylmannosamine kinase (GNE) gene mutations. In this study, we report a novel GNE homozygous point mutation c.1834T>G that results in amino acid substitution of cysteine 6...

Hypothyroid myopathy has so far been reported in long standing cases of hypothyroidism. We describe two adult patients with myopathy associated with acute transient hypothyroidism. Both presented with severe muscle aches and cramps, stiffness and spasms. Muscle enzymes were markedly elevated and electromyography in one patient showed myopathic features. Histological changes were absent in muscl...

Centronuclear myopathy (CNM) is a rare congenital myopathy that is characterized by centrally placed nuclei in the muscle fibers. Three forms of the disease are clinically recognized. The severe neonatal form, the childhood onset form, and an adult-onset form. We report a 50 year old male patient with centronuclear myopathy (CNM) in whom the disease manifested itself in the fifth decade of life...

Muscular involvement in Behçet's disease is rare and there are only a few case reports in the literature. The causes of elevated muscle enzymes in a patient with Behcet's disease are many, including myositis, drug-induced myopathy, metabolic myopathy, and the disease itself. We herein have defined an algorithmic approach to a patient with Behcet's disease and elevated muscle enzymes and report ...

Hypothyroidism's neurological manifestations are uncommon as first symptoms, and they usually appear later in the disease's course.Muscle hypertrophy is a very occurrence hypothyroid people 1. Hoffmann's syndrome kind of hypothyroidism thatmanifests muscle stiffness pseudohypertrophy adults. In most cases myopathy, laboratory tests reveal elevatedlevels enzyme.
