  • how to match snp position to GRCh37 release?

    I have got rs# and position, and download GRCh37 released genome database. SNP position is labeled by ref-assembly. How to translate the ref-assembly position to GRCh37 position?

  • #2
    Depending on database but in general now:
    human primary reference assembly=GRCh37

    If you used dbSNP to get the IDs or find the appropriate position is listed
    If using UCSC correct bp +1 to offset their use of 0-base indexing

      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...
