Sådan læser en genomtest PIK3CA
73
positioner i PIK3CA, hvor ClinVar klassificerer en ændring som patogen eller sandsynligvis patogen
11 af dem (15 %) ligger i regioner, som korte læsninger har svært ved.
- Low mappability (11 steder)Regions where 100 bp or 250 bp reads cannot be placed uniquely.
- Segmental duplications (11 steder)Copies of at least 1 kb sharing at least 90% identity with another part of the genome (paralogues, pseudogenes); reads may align to the wrong copy.
En helgenomsanalyse dækker alle 91,7 kb af PIK3CA, inklusive introner, og ikke kun de 9,3 kb eksoner.
