Eksoner i genets MANE Select-transkripsjon (utgave v1.5), fra NCBI og EMBL-EBI, på referansegenomet GRCh38.
Kromosombånd fra UCSCs GRCh38-ideogram (2022-10-29).
Gener i nærheten fra Ensembl-utgave 116, på GRCh38.
Eksonene utgjør 9,3 kb av genets 91,7 kb, og 3 207 av disse basene koder for proteinet.
Slik leser en genetisk test PIK3CA
73
posisjoner i PIK3CA der ClinVar klassifiserer en endring som patogen eller sannsynligvis patogen
11 av dem (15 %) faller i områder som korte avlesninger sliter med.
- Low mappability (11 posisjoner)Regions where 100 bp or 250 bp reads cannot be placed uniquely.
- Segmental duplications (11 posisjoner)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 helgenomsekvensering dekker alle 91,7 kb av PIK3CA, inkludert introner, og ikke bare de 9,3 kb med eksoner.
