Nhaka Yakakosha yeHofu
Chirwere cheNorrie chirwere chinotora nhaka chinotungamirira kupofu pakuzvarwa kana munguva pfupi pashure payo, kunzwa kurasikirwa, uye kukurumidza kunonoka. Kuchinja kwemukati muNPP gene pane X chromosome inokonzera chirwere cheNorrie. Iyo yakatora nhaka mune imwe X-inowirirana yakawandisa muenzaniso . Nokuda kwechikonzero ichi, chirwere cheNorrie chinokanganisa zvikuru vakomana. Hazvizivikanwe kuti nhamba yeNorrie inowanzoitika sei.
Zviratidzo
Zviratidzo zvechirwere cheNorrie zvinogona kusanganisira:
- bofu mumaziso maviri pakuzvarwa kana munguva pfupi
- vadzidzi vanoita vatsvene apo chiedza chakavhenekera pavari (leukocoria)
- ruvara rwemaziso (irises) dzinogona kuderera mushure mokuberekwa
- maziso eziso angaderera shure kwekuberekwa
- kumira mumakondomu emaziso (kutadza)
- unyoro kusvikira kurasikirwa kwekunzwa kunogona kukura nekufamba kwenguva
- kubudirira kunonoka mumakumbo emakumbo sekugara nekufamba
- unyoro kusvika pakuenzanisa kutadza kwepfungwa
Chirwere cheNorrie chinogonawo kukonzera matambudziko nekupararira, kufema, kudya, uye excretion.
Kuziva
Kana zviratidzo zvomwana zvinoratidza chirwere cheNorrie, chiremba weziso ( ophthalmologist ) achaongorora meso emwana. Kana chirwere chaNorrie chikavapo, chiremba anoongorora maziso achaona retina isingasviki kumashure kweziso. Kuongororwa kunogonawo kusimbiswa nemaitiro ekuongorora kuchinja kweNPP gene pane X chromosome.
Kurapa
Hapana hutano hwakananga hwechirwere cheNorrie uye hapana nzira yokumisa kana kudzosera kurasikirwa kwemaonero uye zvichida kunzwa.
Kurapa kunogona kudiwa kune zvimwe zvinetso chirwere chinogona kukonzera, zvakadai sekufema kana kupera. Mwana ane chirwere chaNorrie achange achida dzidzo yakakosha nekuda kwekusaona kwake nekuona kurasikirwa.
