Chilichonse chomwe chimatipatsa ife tchuthi, maso a tsitsi, tsitsi ndi khungu, zimakhalapo chifukwa cha kukhalapo kwa melanin m'maselo. Kupezeka kwake kulibe vuto la chibadwa cha mtundu wobadwa. Albinism mwa anthu si yachilendo, imachokera kwa makolo, makamaka ngati onsewo akunyamula jeni la mutated kwambiri.
Mitundu ndi zifukwa za ulubino
Chizindikiro cha melanin chimachokera ku puloteni wapadera - tyrosinase. Kutsekedwa kwa chitukuko chake kungayambitse kusowa kwathunthu kwa pigment kapena kusowa kwake, komwe kumayambitsa albinism.
Njira zothandizira matendawa zimagawidwa kukhala autosomal komanso autosomal recessive mtundu. Malinga ndi mtunduwo, matendawa amagawidwa motere:
- Ulubino wosiyana . Pofuna kuti matendawa asonyezedwe, ndikwanira kuti kholo limodzi likhale ndi jini yambiri.
- Ulubino wonse . Zimangokhalapo pokhapokha ngati abambo ndi amayi ali ndi gene mutated mu DNA.
- Albinism yosakwanira . Icho cholandira monga autosomal chachikulu komanso autosomally recessive.
Malingana ndi mawonetseredwe a kachipatala, pali matenda othetsera ophthalmic and ocular. Tiyeni tione mwatsatanetsatane
Olubinism ya diso
Matenda amtundu uwu ndi akunja osadziwika. Amadziwika ndi zizindikiro zotsatirazi:
- zochepetsedwa;
- mphukira ;
- nystagmus - kusuntha kosasamala kwa maso.
Khungu ndi tsitsi zimakhala zachibadwa kapena zowala pang'ono kuposa za achibale.
Ndikoyenera kudziwa kuti amuna okha ndi omwe amakhudzidwa ndi maso a maso, pamene akazi ndi okhawo omwe amanyamula.
Oculomotor albinism kapena HCA
Pali mitundu itatu ya mawonekedwe a alubino:
- HCA 1. Fomu iyi imalingaliridwa ndi gulu lachiwiri A (kusungunuka sikumapangidwira konse) ndipo B (kusungunuka kwapadera kumapangidwa mosakwanira kuchuluka). Pachiyambi choyamba, tsitsi ndi khungu sizimakhala zonyezimira (zoyera), kukhudzana ndi dzuwa kumayambitsa kuyaka, iris ndi yowonekera, mtundu wa maso umawoneka wofiira chifukwa cha mitsempha yambiri yamagazi. Mtundu wachiwiri umaphatikizapo kufooka kwa mtundu wa khungu, komwe kumakula ndi msinkhu, komanso kukula kwa tsitsi, iris;
- HCA 2. Chizindikiro chokhacho ndi khungu loyera kupatula mtundu wa wodwalayo. Zizindikiro zina zimakhala zosiyana - tsitsi lachikasu kapena lofiira-lachikasu, loyera kapena lakuda maso, ngati mawonekedwe a khungu ndi dzuwa;
- HCA 3. Mtundu wa alubino wosawerengeka kwambiri ndi maonekedwe osadziwika. Khungu, monga lamulo, liri ndi mtundu wa chikasu kapena dzimbiri-bulauni, ngati tsitsi. Maso - bulauni-bulauni, ndi maonekedwe owonetsa amakhalabe osowa.
