Human Mitochondrial Genome Draft tracks last updated 26 August 2001: The mammalian mitochondrial genome is a very natural extension of the nuclear genome that might simply be included as an "extra chromosome" to the existing human and mouse browsers. It is also a good choice for development of custom tracks, a proteome/mutational browser, and stand-alone web browser mirror issues because it factors out large file, assembly, draft, and recomputation issues, isolating core mirror/mysql database procedures. While the human and mouse mitochondrial genomes are finished, many dozen mammal and early eukaryote projects are underway. The mitochondrial genome was derived billions of years ago from an internalized alpha-proteobacteria, so the project also serves as a model for implementing the estimated 460 bacterial and archael genomes projects underway. There already exist a number of superb mitochondrial sites furnishing well-maintained data of all types. Thus this project does not have to search the research literature for data but rather, since the data is not always in a format suitable for a custom track, develop automatic means of stripping out the content of these sites (and by implication, unattended maintainence of the mitochondrial genome browser).

Final Diagnosis Mitochondrial Myopathy Clinical discussion: The differential diagnosis for a young patient with asymmetrical palpebral ptosis and diplopia, with no limb or trunk weakness includes mainly myasthenia gravis (or a congenital myasthenic syndrome), or a mitochondrial disorder. The electrodiagnositic studies suggest a myopathy rather than a neuromuscular transmission disorder. The diagnosis of myasthenia gravis is less likely in this case in view of the negative acetylcholine receptor antibodies, and negative tensilon test. The muscle biopsy was, therefore, done to find evidence for a myopathy. Microscopic discussion: This biopsy showed a florid mitochondrial myopathy as evidenced by the many "ragged" red fibers. It was consistent with the clinical phenotype of a progressive external ophthalmoplegia syndrome which is often caused by mitochondrial dysfunction. The vast majority of these cases show a common large deletion of the mitochondrial DNA. In this patient, the analysis for mitochondrial deletions was negative. Rarely, point mutations in the mitochondrial genome (such as in the isoleucine t-RNA gene) have been associated with this phenotype (Taylor RW et al, 1998, Biochem Biophys Res Commun 243:47-51). There exists an autosomal dominant progressive external ophthalmoplegia syndrome in which mitochondrial DNA deletions co-segregate with an autosomally derived factor which is thought to predispose to mitochondrial DNA deletions (Moslemi AR, et al., 1996, Ann Neurol 40:707-713).

Final Diagnosis Mitochondrial Myopathy The differential diagnosis of this patient's weakness, ptosis, and progressive opthalmoplegia includes two main possibilities: myasthenia gravis (or other neuromuscular junction disorder) and a mitochondrial disorder. The fatigability on examination and the positive tensilon test argue in favor of the diagnosis of myasthenia gravis. However, this diagnosis was not supported by the negative acetylcholine receptor antibodies and the electrodiagnostic studies, which have sensitivities of 85% and over 90% respectively in myasthenia gravis. Mitochondrial disorders can also show progressive external opthalmoplegia and weakness, but are more rare. The muscle biopsy was done to verify the possibility of a mitochondrial myopathy and, in fact, confirmed it. Microscopy Discussion: The biopsy shows a florid mitochondrial myopathy. The clinical phenotype corresponds to the so-called progressive external ophthalmoplegia plus pattern. In the vast majority of these cases, a common deletion in the mitochondrial DNA can be found. In this patient however, mitochondrial DNA analysis failed to show such a defect or for that matter any of the common mutations known to occur in mitochondrial diseases. This raises the possibility of a defect in one of the nuclear-encoded subunits of cytochrome oxidase being responsible for this disease. Alternatively, this could represent a novel mitochondrial DNA mutation. The patient's family history was not helpful in that regard.

Tolosa Hunt Syndrome OCULAR MOTILITY DISORDERS MeSH description Disorders that feature impairment of eye movements as a primary manifestation of disease. These conditions may be divided into infranuclear, nuclear, and supranuclear disorders. Diseases of the eye muscles or oculomotor cranial nerves (III, IV, and VI) are considered infranuclear. Nuclear disorders are caused by disease of the oculomotor, trochlear, or abducens nuclei in the brain stem. Supranuclear disorders are produced by dysfunction of higher order sensory and motor systems that control eye movements, including neural networks in the cerebral cortex; basal ganglia; cerebellum; and brain stem. Ocular torticollis refers to a head tilt that is caused by an ocular misalignment. Opsoclonus refers to rapid, conjugate oscillations of the eyes in multiple directions, which may occur as a parainfectious or paraneoplastic condition (e.g., opsoclonus-myoclonus syndrome).

Case Index PATIENT CASE STUDIES Case 12 2/23/99 Myopathy Case discussion This 18-year old female was evaluated for ophthalmoplegia and progressive muscle weakness. At the age of 6 years she was noted to have a squint and was given glasses. At seven she complained of double vision that gradually resolved. She did reasonably well until her early teens when she found herself unable to compete with other children at play. Approximately one year prior double vision recurred. For the past 6 months she complained of progressive generalized weakness and has difficulty rising from a seated to standing position. Summarize the Case in 1-2 sentences. 18 year-old female presents with progressive external opthalmoplegia of 12 years, progressive proximal muscle weakness for the last six months, pigmentary degeneration of the retina, and an incomplete heart block apparent on examination. In addition, ataxia, short stature, and ptosis were noted, although fatiguability, mental status changes, and family history were all absent. good, a bit on the long side

Summary and Discussion Albert Yen, M.D. Resident, Department of Neurology Diagnosis: CIDP involving Ocular Cranial Nerves The key issue was whether or not the patient's diplopia was related in etiology to her progressive weakness. Conditions which can cause both extremity weakness and ophthalmoparesis include: The EMG revealed a polyneuropathy, not myopathy or neuromuscular junction deficit. The absence of a decremental response during repetitive nerve stimulation and the negative Tensilon test also did not support this diagnosis. Moreover, this would be a late age for the initial presentation of MG. Diabetes: Although diabetes can cause almost any type of neuropathy, the most common pattern is a distal, symmetrical sensorimotor polyneuropathy that is primarily axonal in nature. Cranial nerve infarcts may lead to eye motility problems in diabetics, but this usually involves an acute, painful onset of ophthalmoparesis, and would be unlikely to involve four separate cranial nerves. In this patient, both the glucose tolerance test and the glycosylated hemoglobin level were normal, effectively ruling out diabetes. The Miller Fisher variant accounts for about 5 percent of GBS cases and is characterized by total external ophthalmoplegia, ataxia, and areflexia. Elevated anti-GQ1b ganglioside antibodies are consistently found. In this patient, the progressive extremity weakness for several months prior to the onset of diplopia is not consistent with GBS.

Aktuelle Tagungsinformationen News and Updates Anmeldung zur Tagung Registration ... DOG Homepage Diagnostic and Therapeutic Problems in Chronic Progressive External Ophthalmoplegia (CPEO) Sommer F., Fötzsch R., Wollensak G., Pillunat L. E., Universitätsklinikum Carl Gustav Carus, Klinik und Poliklinik für Augenheilkunde (Dresden) Universitätsklinikum Carl Gustav Carus, Technische Universität Dresden, Neurologie (Dresden) Purpose: Strictly CPEO is defined as paralysis of the external ocular muscles combined with ptosis. In ophthalmoplegia-plus-syndrome or Kearns-Sayre-Syndrome additional neurological or muscular deficits can be observed may, however, sometimes even decades after the beginning of ocular symptoms. Method: Three patients with classical CPEO and one patient with Kearns-Sayre-Syndrome where included in the present study. The clinical examinations included electromyography, various serological parameters and histological biopsies. Results: The onset of ocular symptoms with divergent strabism and ptosis could be dated back to the age of 7, 27, 38 and 44 years starting on one eye and progressing slowly over years to both eyes. Almost complete restriction of ocular motility („freezing“) was reached after 10, 21, 29 and 31 years after the first symptoms. In the Kearns-Sayre-Syndrome patient general decrease in cardio-respiratory fitness and occasional collapses were noted. In three patients ptosis and strabism surgery led to the relief of the ocular symptoms. Conclusions: In CPEO respectively Kearns-Sayre-Syndrome the onset of the disease is variable and often at an older age. The final correct diagnosis is often delayed due to the mild beginning of the symptoms and the slow progression of the paralyses . In suspicious cases, early EMG and muscle biopsy examination may facilitate the diagnosis. Because of the progressive character of the disease, corrective muscle surgery should be considered with caution.

Surgical Management of Strabismus Associated with Chronic Progressive External Ophthalmoplegia David K. Wallace, M.D.* and Derek T. Sprunger, M.D. Indiana University, Indianapolis, IN *University of North Carolina, Chapel Hill, NC Introduction: Because patients with chronic progressive external ophthalmoplegia (CPEO) may require extraocular muscle surgery, the clinical characteristics and the surgical management of the types of strabismus associated with CPEO were examined. Methods: Five patients with CPEO and strabismus requiring extraocular muscle surgery were reviewed, with attention to symptoms (including diplopia), preoperative and postoperative ocular motility, types of surgeries, effect of other treatment modalities (e.g. prism therapy, oculinum injections), and associated ocular and/or systemic conditions. Results: Three patients complained of diplopia prior to surgery. Two patients presented with esotropia, one with exotropia, and two with hypertropia. Four of five patients required only one surgery for their strabismus, while one patient required multiple surgeries to achieve alignment. No surgical complications were encountered. Two patients had Kearns-Sayre syndrome and one patient had oculopharyngeal dystrophy. Conclusions: CPEO may have clinical characteristics similar to myasthenia gravis and/or thyroid ophthalmopathy. Patients with CPEO and strabismus may benefit from extraocular muscle surgery to improve alignment and relieve diplopia. In addition, prism therapy and/or oculinum injections may be useful adjunct to surgery.

Differential diagnosis of Blepharoptosis: Blepharoptosis can be classified as being congenital or aquired, and further subclassified into myogenic, aponeurotic, neurogenic, neuromuscular junction, and mechanical etiologies. Levator dystrophy is the most common cause of congenital ptosis and aponeurotic defects are commonly implicated in aquired ptosis. Neurogenic etiologies include cranial nerve III palsy, Horner's syndrome, and aberrent regeneration. Myasthenia gravis is due to an abnormality at the neuromuscular junction, and is characterized by diurnal variation and variable symptoms. Mechanical ptosis may be secondary to eyelid lesions and cicatricial conjunctivitis. Lastly, one must consider pseudoptosis which is generally caused from orbital volume deficits such as with anophthalmia and phthisis bulbi, as well as with contralateral lid retraction. Considering the history and examination findings, the differential was narrowed to myogenic ptosis and myasthenia gravis. Acquired myogenic ptosis includes myotonic dystrophy, chronic progressive external ophthalmoplegia, and oculopharyngeal dystrophy. Myotonic dystrophy is an autosomal dominant muscular dystropy with onset in the second decade of life, characterized by delayed relaxation of skeletal muscles after contraction. Symptoms include blepharospasm, which is followed by muscle atrophy, ptosis and weakness of orbicularis oculi. There are slow saccades and ophthalmoplegia often develops. The pupils are often miotic and sluggish to light and near. Characteristic Christmas tree cataracts (fine anterior and posterior subcapsular colored crystals) are found in virtually 100% of patients. There may be associated cardiac disease, dysphagia, constipation, incontinence, mental retardation, hyperostosis, scoliosis, testicular atrophy, and baldness.
