  • Problem with alignment with pseudogenes

    Hi All,

    I am interested in discovering variants in a gene that has 4 pseudogenes on the same chromosome and 1 pseudogene on another chromosome. The sequence identity between the parent gene and the pseudogene ranges from 88% to 95%.

    Currently we have paired-end reads and the aligned bam files for the chromosome that contains the gene. How do I avoid mapping the reads to pseudogenes?

    Thanks!

    You need to only use reads whose mates map in unique sequence in the region of the genome next to your real gene.

    If the duplicated region is very large, this just might not work.

      Recent Advances in Sequencing Analysis Tools
      by seqadmin


      The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

      Essential Discoveries and Tools in Epitranscriptomics
      by seqadmin




      The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...
