  • Illumina Whole Exome coverage

    Before I send some samples off for whole exome sequencing is there a way to check the coverage of the region that I'm interested in?

    Ideally a track on UCSC genome browser or the Savant genome browser would be great.

    Thanks

    I like to load the BED file of the capture probes in IGV and take a look.

    If you go to Illumina's iCom site, go to downloads and do a .bed search. Download the following, you can load into UCSC, Savant, IGV, etc. and take a look.

    TruSeq Exome Targeted Regions BED file

    This gzipped file (TruSeq_exome_targeted_regions.hg19.chr.bed.gz) contains information on the Targeted Exons in the TruSeq Exome product (201,071 regions). It can be loaded into UCSC Genome Browser to visualize specific target regions or to compare with other data of interest accesible via UCSC Browser's tables function. This BED file has 6 columns 1 chromosome 2 chromStart (zero-based) first position of the feature 3 chromEnd (zero-based) first position after the feature 4 name (chromosome:chromStart-chromEnd:gene) 5 length (chromEnd-chromStart) 6 strand (all targets mapped to the plus strand = +)

      Thanks for the suggestion, but to get the data from the iCom site you need an account, and you can't seem to get an account without previously placing an order.

      Is the BED file available on a FTP somewhere?

      Thanks

            Now that I have the Illumina whole exome BED file and a BED file of the region of interest, is there a way to get the computer to subtract one from the other to give me regions that are coding but not covered by the Illumina data?

              Exploring the Dynamics of the Tumor Microenvironment
              by seqadmin




              The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

              Exploring Human Diversity Through Large-Scale Omics
              by seqadmin


              In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
