Figure 31 The top panel of the variant tab provides a summary of information about this variant (in this example, a SNP).

The top panel (shown in Figure 31) is shown in all variant tab views. It provides basic information about the variant. 

  • Most severe consequence. The most severe predicted consequence of this variant.
  • Alleles. The possible alleles are shown. The reference allele (the nucleotide in the reference sequence) is listed first. In this case the reference allele is ‘G’. Note this may not be the major allele.
  • Location. The genomic coordinates of the variant.
  • Evidence status. A simple summary of the evidence supporting a variant as a guide to its potential reliability.
  • HGVS name. A specific name from the HGVS project.
  • Synonyms. Any other IDs associated with this variant are shown.
