ʻO nā mea a pau e hāʻawi ai iā mākou ke kanaka, ka lau o nā maka, ka lauoho a me kaʻili o kaʻili, no ka hikiʻana mai o ka melanin i loko o nā pūnaewele. ʻO kona heleʻana, he hōʻailona pilikino ia o kaʻano likeʻole. ʻAʻohe mea maʻamau i ka Albinism i loko o nā kānaka, ua iliʻia mai nā mākua mai, akā, ināʻo lāua e lawe ana i ka gen mutation.
Nāʻano a me nā kumu o ka albinism
ʻO ke kuhi o melanin no kekahi enzyme maʻamau - tyrosinase. ʻO ka'āpana o kona uluʻana e hiki ke alakaʻi i ka hemahema o ka puaʻaleʻa aiʻole kona hemahema, e hoʻonāukiuki i ka albinism.
Hoʻomoheleʻia nāʻano o ka hoʻoilina o ka maʻi i ka mana autosomal mana a me kaʻano o ka hopena autosomal. Ma muli o keʻano, ua hoʻohālikelikeʻia nāʻano pilikino e like me kēia:
- Māhele haʻahaʻa . No kaʻikeʻana i ka maʻi, ua lawa ka loaʻaʻana o kekahi makua me kahi pūnāwai.
- Ka paukū albinism . Aia wale nō i ka hihia ke hoʻopauʻia ka makua kāne a me ka makuahine ma ka DNA.
- ʻO ka albinism i hoʻopihaʻoleʻia . Ua hoʻoiliʻiaʻo ia ma keʻano he mana autosomal a me ka hoʻomaha loa.
E like me nā hōʻailona hōʻike, aia kekahi ophthalmic a me kaʻano o ka maʻi ocular. E noʻonoʻo nui kākou
'Aiʻaka maka
ʻO kēiaʻano maʻi i waho a kokoke iʻikeʻoleʻia. Hōʻikeʻia kēia mau hōʻailona:
- ka'āpana kiʻiʻike liʻiliʻi;
- nā strabismus ;
- nystagmus - ka neʻeʻana o ka maka.
ʻO kaʻili a me ka lauoho e noho maʻamau a maʻalahi paha ma mua o ka pili o ka pilina.
He mea pono eʻike i nā kānaka wale nō e pili i ka albinism, akāʻo ka wahine wale nō e lawe i ia mea.
Oculomotor albinism a iʻole HCA
ʻEkoluʻano i manaʻoʻia heʻano albinism:
- HCA 1. Hōʻikeʻia kēiaʻano me ka hapalua A (ʻo ka melaninʻaʻole i hanaʻia i nā mea a pau) a me B (ua huaʻia ka melanin i ka nuiʻole). I ka hihia mua,ʻaʻole i hoʻonani ponoʻia ka lauoho a me kaʻili (keʻokeʻo), kūkili me ka lā o ka lā, ua maopopo ka iris,ʻo ke kele o nā maka uaʻike i kaʻulaʻula no nā ipu blood translucent. ʻO ka lua o ka mea i hele pū me ka pigmentation palupalu o kaʻili, ka mea i hoʻonui i ka makahiki, a me ka nui o ka lauoho lauoho, iris;
- HCA 2.ʻO kahi hiʻohiʻona wale nō kaʻili keʻokeʻo me ka nānāʻole i ka māmā o ka maʻi. ʻO nā mea'ē aʻe heʻanoʻokoʻa - he melemele a heʻulaʻula-lauoho lauoho, heʻeleʻele aniani paha, he mau uliuli paha, keʻano o nā momona i nā wahi hulina o kaʻili me ka lā;
- HCA 3. Keʻano o ka albinism me kaʻikeʻole i nā hōʻike. ʻO kaʻili, ma keʻano he kūlana, he hue melemele a'ōhū-ʻeleʻele paha, e like me ka lauoho. ʻO nā maka - bluish-brown, a me ka'āpanaʻike i mauʻia.
