Abstract |
PURPOSE We have evaluated the mutations of the OPTN gene, which has been reported to be associated with the normal tension glaucoma (NTG). METHODS: The OPTN gene was analyzed in 53 patients with NTG and 40 normal subjects. Genomic DNA was extracted from the blood samples of each patients, exon 5 and exon 6 of the OPTN gene were amplified by PCR and DNA sequencing was performed. RESULTS: No mutation was found in normal subjects. But three kinds of point mutation (G412A, C459T in exon 5, G577C in exon 6) were found in 7 patients with NTG. CONCLUSIONS: We report the novel point mutations of OPTN gene in NTG patients. This shows the possibility of diagnosis of NTG by detecting the mutation of OPTN gene. |
