Hikileʻaleʻa nā chromosomes 21. Wahi a nāʻikepili helu,ʻikeʻia kēlāʻano hihia 1 manawa no nā 600-800 hānau. I ka manawa like, ua hōʻoiaʻia ka uluʻana o ke kūʻana o ka maʻi i ka ulu o ka makahiki o ka wahine e hele.
He aha nā kumu o ka hoʻomohalaʻana i nā chromosoma?
I mea e maopopo ai i keʻano o nā chromosomes 21, pono eʻike i nā kumu a me nā hiʻona o kēia maʻi. Aia a hiki i kēia manawa,ʻaʻohe kumu kūpono no ka uluʻana o nā maʻi. He nui ka poʻeʻepekema e hōʻea i ka hopena i ka hopena o kēia maʻi ma muli o ka nui o nā pilina ma waena o kēlā me kēia iwi, aʻo ia ka hopena i ka hananaʻana. I kēia hihia, e lilo nāʻano maʻamau iʻoi aʻe kaʻoihana. ʻO ka hopena o ka pauʻole iʻikeʻia,ʻo ka hoʻonuiʻana i ke kino, e pili ana i kahi o nā psychoemotional, ua hoʻopauʻia. No nā 400 genes i noho ma 21 mau kromosoma,ʻaʻole i hoʻokumuʻia ka hapanui o kaʻoihana, a he mea paʻakikī keʻike i ke kumu.
ʻO ka mea wale nō paha, i aʻo i kahi pilikino no ka uluʻana o ka maʻiʻo ia ka makahiki o nā mākua. No laila, i ka manawa o ka noiʻi, uaʻikeʻia i nā wāhine i 25 mau makahiki ke kūpono i ka hānauʻana me kahi maʻi Down syndrome he 1/1250, i ka makahiki 35 - 1/400, a ma nā makahiki 45 he 1 o 30 mau keiki i hānau i kēia maʻi. I ka manawa like, hiki i ka loaʻaʻana o ke keiki me kēia maʻi i nā mākua me ka maʻi likeʻole he 100%. Akā, inā hānau kahi keiki me Down's Syndrome i nā mākua olakino, hiki i ka hapalua o nā keiki me nā maʻi likeʻole he 1%.
Pehea eʻikeʻia ai nā maʻi maʻi?
No ka hoʻokaʻawaleʻana i nā meaʻino a me ka hanana o nā chromosomes 21 i loko o nā wāhine hāpai, ua mālamaʻia kekahi mea iʻikeʻia i ka lā mua o kēlā me kēia hanana iʻikeʻia. Ma keʻano hoʻokahi, ua alakaʻiʻia hoʻi kahi huli e wehe i nā'ōpū no 13 a me 18 mau chromosomes. No ka hanaʻana i kēia, hoʻokōʻia ka hōʻailona koko i loko o ka hala o 10 mau wiki. Hoʻokomoʻia ka'ōpena o ka biomaterial i loko o nā mea hana kūikawā, kahi i hoʻoholoʻia ai kaʻikeʻana o nā pathology.
No ka nānāʻana i ka'ōkiko 21, no ka hopena maikaʻi,ʻo nā hōʻailona o ke kuʻuna, a me nā mea kūponoʻole e like me ka makahiki, ke kaumaha, ka helu o nā hānai, ke komoʻana a iʻole ka heleʻana o nā hanaʻino, a me nā mea'ē aʻe, e mālamaʻia. ua kūkākūkāʻia me kekahi kaukoki.
Eia naʻe,ʻo nā hopena o kēia aʻoʻana,ʻaʻole ia e lilo i kumu kumu nui no kaʻikeʻana i Down syndrome. ʻO nā hopena o ka nānāʻana he hōʻailona ia no ka nānā houʻana i ka'ōpū me ka hoʻohanaʻana i nāʻano hoʻopau. Inā he nui ka nui o nā hana pilikino, hana pinepineʻia ka pāpale pinepineʻana, a me ka pilikino e nānā i nā mea i hōʻiliʻiliʻia.
Iā manawa a iā wai kahi i hāʻawiʻia ai?
- ʻO nā makahiki o ka wahine hāpai he 35 mau makahiki a keu aku;
- ke komo i loko o ka pūnaewele o ka pilikia nui, a me ka hāpaiʻoleʻia o ka hānauʻana;
- nā maʻi maʻi chromosomal, a me nā maʻi kūponoʻole i nā hānau mua;
- ka nohoʻana i loko o kaʻohana o nā maʻi maʻi puʻupuʻu;
- ka nui o nā maʻi i hoʻopiliʻia, ka radiation radiation, a me ka hōʻailona i ka hoʻomakaʻana o ka hāpaiʻana i nā lāʻau lapaʻau me ka hopena.
