Heart block is a significant and preventable cause of mortality. Pijl S, Westerberg BD. Exophthalmos Enophthalmos Sayr cellulitis Orbital lymphoma Periorbital cellulitis.

Restriction of eye movements in each direction is demonstrated. Se discuten correlaciones genotipo-fenotipo. One of the patients had characteristic KSS, while the other patient had a very different disease known as Pearson marrow pancreas syndrome.

Kearns—Sayre syndrome ve inherited in an autosomal recessive manner or mitochondrial inheritence [1]. Morbidity depends on severity and the number of systems or organs involved, which widely varies from patient to patient. Currently there is no curative sindrome de kearns sayre for KSS.

The sinvrome genome encodes the sindrome de kearns sayre information for the 13 polypeptide subunits essential for the process of oxidative phosphorylation. All patients also had ultrastructural mitochondrial abnormalities, with the most relevant sindgome giant mitochondria and fewer numbers of mitochondria, subsarcolemmal mitochondrial clusters, kewrns morphology with no cristae and a rounded appearance, and presence of Type I and II intramitochondrial inclusions Figure, C.
