However, the focus of the book remains clinical, describing symptoms and signs at presentation, how to come to a diagnosis and methods for treatment. As with the previous edition, the book can be used in two main ways. [books.google.com]

The clinical presentation and onset of symptoms is very varied and largely depends on the phenotype that is expressed, which are summarized below. [radiopaedia.org]

Although Alpers-Huttenlocher syndrome has a restricted neuro-hepatic presentation, mutations in this same gene can result in a broad range of clinical presentations that involve not only the brain and liver, but the rest of the central and peripheral [medlink.com]

• Death in Childhood

  The typical course of the disease includes severe developmental delay, intractable seizures, liver failure, and death in childhood. [genecards.org]

• Long Arm

  Genetics The polymerase gamma (POLG) gene (POLG1) is located on the long arm of chromosome 15 and encodes for DNA polymerase γ, while the POLG2 gene, located on the long arm of chromosome 17, encodes for its catalytic accessory sub-unit 2,3,7. [radiopaedia.org]

In acquired myopathies, treatment is targeted toward the underlying cause. Treatment of statin myopathies is dependent on creatine phosphokinase levels and degree of muscle symptoms. Consider lower doses when initiating statin therapy. [clevelandclinicmeded.com]

Treatment and prognosis Treatment is complex and non-curative, with focuses on family education, genetic counseling, symptom management, and supportive care 4. [radiopaedia.org]

The authors conclude that POLG mutations are an important cause of heterogeneous mitochondrial pathology and that more accurate genotype-phenotype correlations allow a more rapid genetic diagnosis and improved prognosis for mutation carriers URL go to [dare.uva.nl]

It also indicates the most probable age of onset, which will serve as the basis for a diagnosis and prognosis for the patient. [mitochondrialdiseasenews.com]

MDDSs have a poor prognosis in the majority of the cases. The outcome is usually better the later the onset of the MDDSs. Key Concepts Paediatric and adult neurologist must be aware of multisystem mitochondrial depletion syndromes (MDDSs). [els.net]

In cases suspected to be a primary inflammatory myopathy, specific autoantibodies can be considered to determine the prognosis and rule out associated conditions. [clevelandclinicmeded.com]

Rhabdomyolysis may also be seen with infectious etiologies, alcohol, and toxic exposures. [clevelandclinicmeded.com]

It is concluded that this novel POLG mutation forms the most parsimonious etiological explanation for the here-described combination of ataxia, major depression, and cardiomyopathy. [dovepress.com]

These data provided the full pathophysiology of the phenotype, including the identification of the genetic etiology and the physiologic changes of reduced mtDNA content inducing mtDNA depletion. [medlink.com]

She also had Global developmental delay with Quadriplegic cerebral palsy and brain atrophy due to unknown etiology. She was having bilateral cataract, nystagmus associated with visual impairment along with hearing loss. [omicsonline.org]

Whilst is evident that POLG does not represent a frequent etiology in PD-like syndromes, it seems not too speculative to hypothesize that alterations in mtDNA fidelity and subsequent impaired protein synthesis likely compromise mitochondrial bioenergetics [bmcmedgenet.biomedcentral.com]
