Whakarāpopototia te tuhinga:  Kua whakarerekētia ngā ira tangata kia puta ai ngā whakarerekētanga ki ngā whakatupuranga o muri, hei te wā tuatahi, e ai ki ngā pūtaiao. Kei te whakareri ngā kairangahau huri noa i te ao i a rātou mō ngā hua o tētahi rangahau nā ngā pūtaiao i Haina i whakaputa i ngā huringa DNA ki ngā pūtau whakatipu. Ahakoa kāore anō kia whakaputaina te pepa pūtaiao, kei te ngū tonu te ao pūtaiao i ngā kōrero kua oti te mahi. He tokomaha nga kaipūtaiao kua whakawehi i te whakaaro, i te wehi ka taea te whakamahi kino ki te tuku i nga matua ki te 'whiriwhiri' i nga ira ka tukuna e ratou ki a ratou mokopuna. Tērā pea kua whakarerekētia ā-ira ngā mokopuna tangata, pēnei i te mea i runga ake nei, mā ngā tikanga whakatika ira hou. E mea ana rātau, ahakoa ko ngā kikokiko i hangaia i runga i tēnei huarahi mō ngā take rangahau anake, ka nui pea ngā pānga ki te tikanga me te haumaru. Kua whakaahuatia e rātau he 'hē, he kore e whakaaetia i runga i te tikanga.' Heoi anō, e tautohe ana ētahi atu ka taea hoki te whakamahi i te hangarau hei whakakore i ngā whānau i ngā mate tuku iho kino pēnei i te cystic fibrosis, i ētahi mate pukupuku rānei. Ka taea e tētahi tikanga whakatika ira e mōhiotia ana ko CRISPR te rapu i roto i te DNA me te whakakapi i ngā ira motuhake, te tango rānei i a rātou. I raro i nga tono i tukuna e Dr Luhan Yang, ka taea te whakamahi i te kiko o te ovarian tangata mai i nga wahine e mahi ana mo te mate pukupuku o te ovarian ki te whiwhi i nga pūtau o te hua. Kātahi ka taea te whakatenatena i ēnei ki te tupu i roto i te taiwhanga i mua i te whakamahi i te CRISPR hei tango i te hapa iranga e pā ana ki te mate pukupuku. Hei tauira, ko te ira BRAC1 hapa, ka hua i te mate pukupuku u me te mate pukupuku ovary. Mā te whakatikatika i tēnei ira, ka taea te whai hauora i te hua. I tēnei wā e kī ana ngā kairangahau me whakamahi anake tēnei mō te rangahau pūtaiao engari ka whakatuwhera i te tūponotanga ki te whakamahi i ngā hua manu i whakarerekētia hei waihanga i ngā pūmua tangata kua tangohia ngā mate tuku iho. E ai ki tētahi pūrongo a te National Post, e mea ana a Pōrero George Church, he tohunga iranga i te Kura Hauora o Harvard, ka whakaputaina he pepa e whakaatu ana i te hangarau. Ka mea ia: 'He pepa mai i Haina. Ki taku whakaaro ehara i te mea...
E whakaponohia ana kua whakarerekēhia e ngā kaipūtaiao i Haina te DNA o ngā pūmua tangata kia taea ai ngā whakarerekētanga te tuku atu ki ngā whakatupuranga o muri mai i roto i te rārangi ira. Kua karanga ngā kairangahau ārahi kia whakatārewatia taua rangahau kia taea ra ano ngā pānga me te haumaru o te hangarau. E whakatūpato ana rātau ko te whakarerekētanga o te rārangi iramutu 'he mea mōrearea, ā, e kore e whakaaetia i runga i te tikanga matatika' E wehi ana ētahi ka taea te whakamahi hē i te tikanga hei waihanga i ngā 'whānau hoahoa'
