Cum citește un test genomic PIK3CA
73
poziții în PIK3CA în care ClinVar clasifică o modificare drept patogenă sau probabil patogenă
11 dintre ele (15 %) se află în regiuni pe care citirile scurte le găsesc dificile.
- Low mappability (11 de situri)Regions where 100 bp or 250 bp reads cannot be placed uniquely.
- Segmental duplications (11 de situri)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.
Un test genomic complet acoperă toți cei 91,7 kb ai genei PIK3CA, inclusiv intronii, nu doar cei 9,3 kb de exoni.
