The mitochondrial haplogroup has been reported to affect the clinical expression of Leber's hereditary optic neuropathy (LHON). The present study aimed to investigate the interaction between mutations and the haplogroup of mitochondrial DNA (mtDNA) in families. Two unrelated families with LHON were enrolled in the study, and clinical, genetic and molecular characterizations were determined in t...
Leber's hereditary optic neuropathy (LHON) is a mitochondrially inherited disease leading to blindness. A mitochondrial DNA point mutation at the 11778 nucleotide site of the NADH dehydrogenase subunit 4 (ND4) gene is the most common cause. The aim of this study was to evaluate the efficacy and safety of a recombinant adeno-associated virus 2 (AAV2) carrying ND4 (rAAV2-ND4) in LHON patients car...
PURPOSE To determine mitochondrial (mt)DNA variants in AMD and age-matched normal retinas. METHODS Total DNA was isolated from retinas (AMD, n = 13; age-matched normal, n = 13), choroid (AMD, n = 3), and blood (AMD, n = 138; normal, n = 133). Long-extension-polymerase chain reaction amplified the full-length ( approximately 16.2 kb) mtDNA genome. Retinal mtDNA was sequenced for nucleotide var...
PURPOSE Reactive oxygen species (ROS) are suspected to play a pivotal role in the pathogenesis of Leber hereditary optic neuropathy (LHON), caused by mutated complex I subunit genes. It seems surprising that optic neuropathy has not been described in animals with a knockout of genes encoding critical anti-ROS defenses. If ROS have a role in the optic nerve injury of LHON, then increasing mitoch...
بیماری lhon شایعترین بیماری میتوکندریایی می باشد که از طریق وراثت مادری انتقال می یابدو شاخصه ی آن بروز نابینایی حاد و یا نیمه حاد در طول دهه ی دوم و یا سوم زندگی میباشد.در حدود 90% از بیماران دارای یکی از سه جهش میتوکندریایی: g3460a t14484c, g11778a, که به ترتیب در ژن های nd6,nd4,nd1 رخ می دهند،می باشند.همچنین در این بیماران وجود complex i deficiency درزنجیره تنفسی میتوکندری نیز اثبات شده است ...
PURPOSE To study mutations associated with Leber hereditary optic neuropathy (LHON) in patients suspected of having this mitochondrial disorder in a Latvian population. Additional aims were to determine the heteroplasmy status of all non-synonymous polymorphisms identified in the current study and to identify the mitochondrial haplogroups of the studied participants because these factors may co...
BACKGROUND Leber's Hereditary Optic Neuropathy (LHON; MIM 535000) is one of the most commonly inherited optic neuropathies and it results in significant visual morbidity among young adults with a peak age of onset between the ages of 15-30. The worldwide incidence of LHON is approximately 1 in 31,000. 95 % of LHON patients will have one of 3 primary mitochondrial mutations, G3460A (A52T of ND1)...
