Study Description

As a part of the ICGC, India has undertaken genomic studies on gingivobuccal cancer of the oral cavity, which is the most prevalent form of cancer among men in India. There are various known environmental (life-style) correlates of this cancer, the most important of which are tobacco chewing and HPV infection. Detailed clinical characterization of the patients, collection of data on demographic and environmental exposures, and isolation of DNA samples from blood and tumor tissues collected from each patient are being done at the Advanced Centre for Research, Treatment and Education on Cancer, Mumbai. Whole genome and other sequencing experiments are being performed at the National Institute of Biomedical Genomics, Kalyani. Whole mitochondria sequencing of 89 patients was performed in this study. The mean depth of sequencing was at least 2500X, but variable across platforms, 2689X and 9894X for amplicon sequencing in Ion Torrent PGM (Tumor-blood pairs=16) and Illumina HiSeq 2500 (Tumor-blood pairs =48), respectively; and, 14,190X for whole genome sequencing in Illumina HiSeq 2500 ...

This dataset pertains to mitochondrial DNA amplicon sequencing of paired DNA samples from gingivo-buccal oral cancer patients. DNA was isolated from the tumor and blood tissues of 89 patients (178 samples). The sequencing libraries were prepared from whole mitochondrial amplicons using Nextera XT DNA Library Preparation Kit (Illumina) and sequenced in Illumina HiSeq platform. The uploaded BAM files are generated by aligning paired-end reads to the mitochondrial reference sequence (rCRS) using ... (Show More)
