  • A question regarding copy number variation

    This may not be the correct place for such a question, but I see people are posting regarding CNV so I may get some help.

    I believe that particular alleles of a gene I am studying may display CNV. Simply, this is related to consistent variances in depth acquired per allele between genotypes (as well as other lines of evidence).

    However, it was commented that if a particular allele was duplicated multiple times, we would expect to see them in the form of closely related haplotypes which have slightly diverged. This is assuming the duplications are ancient. If this was always the case then I can see that identifying paralogs would be easy. However, multiple recent studies have identified CNV based on total sequencing depth of a sequence/region of the genome. I am assuming then that all of the paralogs are identical, as a result of recent duplication or strong concerted evolution?

    So can someone with experience please tell me if you expect/identify duplicated alleles which are identical?

    (note that I am only looking at a 200bp amplicon of the functional region of a coding sequence, maybe paraloges may appear identical where polymorphisms exists outside of the amplicon?)

    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...

    Current Approaches to Protein Sequencing
    by seqadmin


    Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...
