Jak genetický test čte PIK3CA
73
pozic v genu PIK3CA, které ClinVar řadí mezi patogenní nebo pravděpodobně patogenní
Z nich 11 (15 %) leží v oblastech, které krátká čtení obtížně zachycují.
- Low mappability (11 míst)Regions where 100 bp or 250 bp reads cannot be placed uniquely.
- Segmental duplications (11 míst)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.
Celý genom pokrývá všech 91,7 kb genu PIK3CA, včetně intronů, nikoli jen 9,3 kb exonů.
