Exons make up 3.9 kb of the gene's 5.4 kb; 1,530 of those bases code for the protein.

How a genome test reads SOX9

59

positions in SOX9 where ClinVar classes a change as pathogenic or likely pathogenic

None of them falls in a region short reads find hard.

A whole genome covers all 5.4 kb of SOX9, introns included, not only the 3.9 kb of exons.

Where this comes from

  • HGNC: the gene's symbol, name, other symbols and location.
  • MANE Select v1.5, from NCBI and EMBL-EBI: the transcript, its exons and coding sequence.
  • ClinVar and the GIAB stratifications: known disease-causing sites, and the regions short reads find hard.
