Abstract

The main goal is to perform the complete sequencing of the mitochondrial genome in Brazilian patients ( with clinical symptoms of LHON and optic neuropathy of unknown etiology ) . The specific objectives are : To investigate the frequency of secondary mutations , making the phenotype / genotype correlation and explain the variable expression of this condition ; research the haplogroups of patients with molecular changes , and determine new variants related to optic neuropathy . Approximately 100 patients will be evaluated clinically affected by LHON ( 66 cases ) or optic neuropathy of unknown etiology ( 34 individuals ) . In patients who do not submit primary mutations , catches of target genes and Massive Parallel Sequencing will be performed with the Agilent SureSelect Kit using the Illumina HiSeq 2000 platform . This work is expected to obtain the spectrum of mutations related to LHON present in our population , allowing them to optimize molecular diagnostic tests with a view to prognosis , treatment and genetic counseling .
