  • Redundancy in TCGA data

    maf file in TCGA have redundancy on most genes (See below a example). Can anyone help me in this issue? This is not only in mutation annotation format files but also in RNA-seq to. I don't know what this mean.
    Why the same gene is replicated by rows???

    Ex:
    A4GNT 51146 broad.mit.edu 37 3 137843364 137843364 + Silent SNP T C C TCGA-CJ-4882-01A-02D-1429-08 TCGA-CJ-4882-11A-01D-1429-08 Somatic Phase_I Capture Illumina GAIIx
    A4GNT 51146 broad.mit.edu 37 3 137843364 137843364 + Silent SNP T C C TCGA-CJ-4882-01A-02D-1429-08 TCGA-CJ-4882-11A-01D-1429-08 Somatic Phase_I Capture Illumina GAIIx
    A4GNT 51146 broad.mit.edu 37 3 137843364 137843364 + Silent SNP T C C TCGA-CJ-4882-01A-02D-1429-08 TCGA-CJ-4882-11A-01D-1429-08 Somatic Phase_I Capture Illumina GAIIx
    A4GNT 51146 broad.mit.edu 37 3 137843364 137843364 + Silent SNP T C C TCGA-CJ-4882-01A-02D-1429-08 TCGA-CJ-4882-11A-01D-1429-08 Somatic Phase_I Capture Illumina GAIIx

    Thanks a lot

    There's multiple version of KIRC mafs in various directories.
    I'm not sure which one is gospel and which ones are apocryphal.

      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...
