  • How to create test mutant allele in exome bam?

    Hi,

    I would like to create some test data to work up various approaches to exome analysis in rare human Mendelian disorders.

    I would like to modify a 'normal' exome and introduce a 'pathogenic' mutation at a specific locus. There is a mention in the quick guide to VAAST where this this was done to create a test dataset using only one chromosome's worth of data for the DHODH gene with variants as found in the Miller syndrome paper.


    I would like to replicate this, but don't know how to do it. It would be useful to be able to create a variant at different allele frequencies, and be able to test various combination of % variant over the major allele.

    Should I be looking to modify a Sam file, convert to bam then variant call as normal, or just add an extra variant to a VCF file, which would presumably be simpler to do?

    Thanks

    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...
