A miopatia miofibrilar (MMF) descreve um grupo de doenças que afetam os músculos esqueléticos (os que usamos para nos mover) e o músculo cardíaco (o coração). Ela é caracterizada pela desorganização das miofibrilas (estruturas internas dos músculos) e pelo acúmulo de resíduos (produtos de degradação) em forma de depósitos dentro das células musculares. Clinicamente, a MMF geralmente se manifesta com uma fraqueza muscular que piora lentamente. Essa fraqueza começa nos músculos mais distantes do centro do corpo (como os das mãos e pés). No entanto, a doença é muito variável e, em alguns pacientes, pode também afetar os músculos mais próximos do centro (como os do tronco, ombros e coxas), além dos músculos do coração e os envolvidos na respiração.
Introdução
O que você precisa saber de cara
A miopatia miofibrilar é uma doença rara dos músculos e do coração que geralmente começa a se manifestar na idade adulta. As pessoas afetadas costumam sentir uma fraqueza que avança devagar, atingindo primeiro partes distantes como mãos e pés, além de poder atingir a respiração e a função cardíaca. A condição tem causas genéticas que podem passar de pais para filhos ou ocorrer de forma hereditária recessiva. No Brasil, ela não possui um protocolo clínico específico (PCDT) nem remédios próprios dispensados pelo SUS, sendo acompanhada pela rede de saúde de forma geral.

Curadoria gene-doença
fontes oficiaisCardiomyopathy, familial hypertrophic, 10
A hereditary heart disorder characterized by ventricular hypertrophy, which is usually asymmetric and often involves the interventricular septum. The symptoms include dyspnea, syncope, collapse, palpitations, and chest pain. They can be readily provoked by exercise. The disorder has inter- and intrafamilial variability ranging from benign to malignant forms with high risk of cardiac failure and sudden cardiac death. Rarely, patients present a variant of familial hypertrophic cardiomyopathy, characterized by mid-left ventricular chamber thickening.
Malignant hyperthermia 1
Autosomal dominant pharmacogenetic disorder of skeletal muscle and is one of the main causes of death due to anesthesia. In susceptible people, an MH episode can be triggered by all commonly used inhalational anesthetics such as halothane and by depolarizing muscle relaxants such as succinylcholine. The clinical features of the myopathy are hyperthermia, accelerated muscle metabolism, contractures, metabolic acidosis, tachycardia and death, if not treated with the postsynaptic muscle relaxant, dantrolene. Susceptibility to MH can be determined with the 'in vitro' contracture test (IVCT): observing the magnitude of contractures induced in strips of muscle tissue by caffeine alone and halothane alone. Patients with normal response are MH normal (MHN), those with abnormal response to caffeine alone or halothane alone are MH equivocal (MHE(C) and MHE(H) respectively).
Myopathy, myofibrillar, 3
A form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disk and myofibrils, and replacement of the normal myofibrillar markings by small dense granules, or larger hyaline masses, or amorphous material. MFM3 is characterized by progressive skeletal muscle weakness greater distally than proximally, tight heel cords, hyporeflexia, cardiomyopathy and peripheral neuropathy in some patients. Affected muscle exhibits disorganization and streaming of the Z-line, presence of large hyaline structures, excessive accumulation of myotilin and other ectopically expressed proteins and prominent congophilic deposits.
Myopathy, myofibrillar, 8
A form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disk and myofibrils, and replacement of the normal myofibrillar markings by small dense granules, or larger hyaline masses, or amorphous material. MFM8 is an autosomal recessive form, clinically characterized by slowly progressive symmetrical weakness affecting both proximal and distal muscles, with normal to moderately elevated creatine kinase. Mild facial weakness, a high palate, nasal speech, and swallowing difficulties are typical features, mild restrictive lung disease is common, and late-onset cardiac involvement may be present.
Myopathy, myofibrillar, 10
A form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disk and myofibrils, and replacement of the normal myofibrillar markings by small dense granules, or larger hyaline masses, or amorphous material. MFM10 is an autosomal recessive disorder characterized by muscle pain, cramping, exercise fatigue, and progressive muscle rigidity.
Cardiomyopathy, dilated, 1C, with or without left ventricular non-compaction
A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. Cardiomyopathy dilated type 1C is associated with left ventricular non-compaction in some patients. Left ventricular non-compaction is characterized by numerous prominent trabeculations and deep intertrabecular recesses in hypertrophied and hypokinetic segments of the left ventricle.
Myopathy, myofibrillar, 7
A form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disk and myofibrils, and replacement of the normal myofibrillar markings by small dense granules, or larger hyaline masses, or amorphous material. MFM7 is an autosomal recessive form, clinically characterized by early childhood onset of slowly progressive muscle weakness and mild atrophy primarily affecting the lower limbs, associated with joint contractures.
Cataract 43
An opacification of the crystalline lens of the eye that frequently results in visual impairment or blindness. Opacities vary in morphology, are often confined to a portion of the lens, and may be static or progressive. In general, the more posteriorly located and dense an opacity, the greater the impact on visual function.
Myopathy, myofibrillar, 6
A form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disk and myofibrils, and replacement of the normal myofibrillar markings by small dense granules, or larger hyaline masses, or amorphous material. MFM6 is characterized by early-onset of severe, progressive, diffuse muscle weakness associated with cardiomyopathy, severe respiratory insufficiency during adolescence, and a rigid spine in some patients.
Neuronopathy, distal hereditary motor, autosomal dominant 2
A form of distal hereditary motor neuronopathy, a heterogeneous group of neuromuscular disorders caused by selective degeneration of motor neurons in the anterior horn of the spinal cord, without sensory deficit in the posterior horn. The overall clinical picture consists of a classical distal muscular atrophy syndrome in the legs without clinical sensory loss. The disease starts with weakness and wasting of distal muscles of the anterior tibial and peroneal compartments of the legs. Later on, weakness and atrophy may expand to the proximal muscles of the lower limbs and/or to the distal upper limbs.
Myopathy, myofibrillar, 1
A form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disk and myofibrils, and replacement of the normal myofibrillar markings by small dense granules, or larger hyaline masses, or amorphous material. MFM1 is characterized by skeletal muscle weakness associated with cardiac conduction blocks, arrhythmias, restrictive heart failure, and accumulation of desmin-reactive deposits in cardiac and skeletal muscle cells.
Myopathy, myofibrillar, 5
A form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disk and myofibrils, and replacement of the normal myofibrillar markings by small dense granules, or larger hyaline masses, or amorphous material. MFM5 is characterized by onset in adulthood, clinical features of a limb-girdle myopathy, and focal myofibrillar destruction.
Myopathy, myofibrillar, 2A, adult-onset
A form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disk and myofibrils, and replacement of the normal myofibrillar markings by small dense granules, or larger hyaline masses, or amorphous material. MFM2A is an autosomal dominant form characterized by weakness of the proximal and distal limb muscles, weakness of the neck, velopharynx and trunk muscles, respiratory insufficiency, hypertrophic cardiomyopathy, and cataract.

Concurrent FHL1-Related Myopathy and CMT1A Unveiled by Persistent Neuropathic Feature.

Multi-Parametric MRI Approach at 3 T and 7 T for Assessing Skeletal Muscle Pathology in Myofibrillar Myopathies: A Pilot Study.
Myofibrillar myopathies (MFM) form a large group of clinically and genetically heterogeneous protein aggregate diseases. We investigated whether a novel quantitative MRI protocol can reveal new aspects of structural and biochemical muscle pathology in three classic MFM subtypes. MRI of the lower legs was performed in nine MFM patients with filamin-C (FLNC; n = 5), desmin (DES, n = 2) and LIM domain binding 3 (LDB3; n = 2) gene mutations, one patient with non-MFM, filamin-C related distal myopathy (4 males, 6 females, 51.0 ± 7.7 years) and 10 age-matched healthy control subjects (5 males, 5 females, 50.0 ± 11.0 years). 1H MRI at 3 T addressed fatty replacement and edema-like changes as well as quantitative measurements of proton density fat fraction (PDFF) and water T2 relaxation times. 39K/23Na MRI at 7 T was employed to determine apparent tissue potassium and tissue sodium concentrations (aTPC/aTSC). T1-weighted and T2-weighted STIR imaging showed the highest degree of fat replacement in the soleus and gastrocnemius medialis muscle regions and the highest degree of edema-like changes in the extensor regions in all 10 myopathy patients. The lowest degree of fat replacement and edema-like changes was present in the gastrocnemius lateralis muscles. Marked fatty replacement of peroneus muscles was also present in DES-related MFM and FLNC-related distal myopathy. Muscular PDFF values were significantly increased in all MFM patients (p = 0.003 - < 0.001) with 60 and 35 of 63 muscles analysed showing increased mean PDFF (> 10% and > 50%). When excluding the muscles with PDFF > 50%, the median water T2 was significantly increased in all muscle regions of MFM patients with the exception of the tibialis anterior and posterior muscles. Fat-corrected aTSC values in MFM patients were significantly increased compared to healthy controls (55.6 ± 16.3 mM vs. 23.2 ± 5.5 mM, p < 0.001) in all muscles but peroneus muscles, whereas fat-corrected aTPC values were reduced in all muscles except for gastrocnemius lateralis, tibialis posterior and peroneus muscles (75.4 ± 13.3 mM vs. 108.9 ± 9.9 mM, p < 0.001). Quantitative PDFF measurements and water T2 mapping serve as valuable tools to objectively quantify fat and edema-like changes in MFM. Furthermore, changes in potassium/sodium ion balance in the lower leg muscles of MFM patients could serve as new markers to quantify the extent of biochemical changes in individual muscle regions. Further longitudinal evaluation is required to validate whether they are sensitive to changes prior to a high degree of fat replacement.
Anaesthetic Management of a Patient With LDB3-Associated Myopathy Undergoing Prostate Biopsy Under Total Intravenous Anaesthesia: A Case Report.
Mutations in the LDB3 gene are implicated in myofibrillar myopathy and cardiomyopathy. Consider cardiac conduction defects and the muscle's sensitivity to some anaesthetics when providing anaesthesia in the perioperative period. We present the anaesthetic management of a 76-year-old man with genetically confirmed LDB3 mutation who presented for prostate biopsy with a background of progressive distal myopathy, mild cardiac involvement, and normal activities of daily living (ADL), undergoing anaesthesia using total intravenous anaesthesia (TIVA) to avoid the use of volatile agents or neuromuscular blockers. In this patient with a history of LDB3-associated myopathy, the use of TIVA provided a safe and effective technique of anaesthesia, and reinforced the need for an individualised anaesthetic strategy in neuromuscular disease (NMD).

Novel in-frame variant in DES (p.Glu353dup) causes myofibrillar myopathy: clinical, in silico and functional studies.
Desmin (DES) is a major intermediate filament protein involved in the structural integrity and function of striated muscles. Pathogenic mutations in DES are predominantly missense variants, causing isolated cardiomyopathy and combinations of myopathy and cardiomyopathy. In-frame insertions are very rare and usually classified as variants of uncertain significance or likely pathogenic due to limited predictive and/or experimental evidence. This study describes a novel heterozygous in-frame insertion in exon 6 of DES (RefSeq NM_001927.4:c.1059_1061dup) identified in an Argentine family with myofibrillar myopathy (MFM). This mutation results in the duplication of a glutamic acid residue at position 353 (NP_001918.3:p.(Glu353dup)), in the 2B subdomain of the central rod domain. Clinical, computational and functional analyses were performed to study the pathogenicity of this variant. Clinically, the index patient exhibited hallmark MFM features, including progressive muscle weakness, atrophy and fatty muscle replacement. In silico analyses of molecular dynamics revealed that p.Glu353dup alters DES dimer assembly by stabilising an aberrant coiled-coil conformation, a mechanism not previously proposed for DES mutations. Functional studies in HEK293T cells and C2C12 myocytes suggested that the p.Glu353dup variant induces aberrant DES aggregation, confirming its detrimental effect on filament organisation. These findings are consistent with the idea that p.Glu353dup is a pathogenic variant, supported by clinical studies, in silico protein modelling and functional evidence, highlighting the impact of in-frame insertions on DES filament homeostasis. By providing computational and experimental evidence, this study expands our understanding of desminopathies and offers new perspectives for pathogenicity assessment of uncertain DES variants.
