12. Interpretation of genetic variants becomes the issue
“Functional studies can be a powerful tool in
support of pathogenicity”
Richards et al., Genet Med. (2015)17:405-24
Variant classification:
1. Benign
2. Likely benign
3. Uncertain significance
4. Likely pathogenic
5. Pathogenic
Guidelines American College of Medical Genetics and Genomics (ACMG)
More sequence data =
more unknown variants

22. High need to bring clinical X-omics to higher level
• Technologies: Quality, harmonised, standardised, cheaper, higher throughput
• Translation: Clinical and regulatory acceptance
• Genomics is quite advanced
• Proteomics, metabolomics (and other omics) much less so
