M\u00f5ned lapsed on juba surnud ja vaid v\u00e4hesed mutatsiooni p\u00e4rinud p\u00e4\u00e4sevad oma eluajal v\u00e4hist, vahendab BBC News.<\/p>\n
Spermat m\u00fc\u00fcnud Taanis<\/a> asuv European Sperm Bank teatas, et tunneb perekondadele, keda see puudutab, s\u00fcgavalt kaasa, ja tunnistas, et spermat kasutati m\u00f5nes riigis liiga paljude laste sigitamiseks.<\/p>\n Asja uurisid 14 avalik-\u00f5iguslikku ringh\u00e4\u00e4lingut Euroopa Ringh\u00e4\u00e4lingute Liidu (EBU<\/a>) uuriva ajakirjanduse v\u00f5rgustiku osana.<\/p>\n Sperma tuli anon\u00fc\u00fcmselt mehelt, kellele maksti selle annetamise eest, kui ta oli tudeng, alates 2005. aastast. Tema spermat kasutati seej\u00e4rel umbes 17 aastat.<\/p>\n Mees ise on terve ja l\u00e4bis k\u00f5ik doonoritele kohustuslikud kontrollid. M\u00f5nede tema rakkude DNA oli aga juba enne s\u00fcndi muteerunud. See kahjustas geeni TP53, mis m\u00e4ngib otsustavat rolli keharakkude v\u00e4hirakkudeks muutumise takistamisel.<\/p>\n TP53 ohtlikku vormi sisaldab kuni 20% doonori spermast. Igal mutatsiooniga sperma abil sigitatud lapsel on aga mutatsioon igas keha rakus.<\/p>\n Seda nimetatakse Li Fraumeni s\u00fcndroomiks ja sellega kaasneb 90%-line v\u00f5imalus saada v\u00e4hk eriti lapsep\u00f5lves ja ka rinnav\u00e4hk hilisemas elus.<\/p>\n Selle s\u00fcndroomiga inimesed vajavad keha ja aju magnetresonantsuuringuid igal aastal ning k\u00f5hu ultraheliuuringuid, et kasvajaid tuvastada. Naised lasevad tihti rinnad eemaldada.<\/p>\n H\u00e4iret t\u00f5stsid arstid, kes n\u00e4gid spermadoonorlusega seotud v\u00e4higa lapsi ja teatasid sellest Euroopa Inimgeneetika Seltsile.<\/p>\n Uurivad ajakirjanikud on kindlaks teinud v\u00e4hemalt 197 last, kes on selle doonori sperma abil sigitatud, aga see ei pruugi olla l\u00f5plik number. Pole teada, kui palju lapsi on p\u00e4rinud muteerunud geeni.<\/p>\n Prantsusmaal<\/a> asuva Roueni<\/a> \u00fclikooli haigla v\u00e4higeneetik Edwige Kasper \u00fctles, et on juba palju lapsi, kellel on tekkinud v\u00e4hk ning on lapsi kellel on kaks erinevat v\u00e4hki ja m\u00f5ni on juba v\u00e4ga varases eas surnud.<\/p>\n Doonori spermat kasutati 67 viljakuskliinikus 14 riigis: Albaanias<\/a>, Belgias<\/a>, Gruusias<\/a>, Hispaanias<\/a>, Iirimaal<\/a>, Islandil<\/a>, Kreekas<\/a>, K\u00fcprosel<\/a>, Poolas<\/a>, P\u00f5hja-Makedoonias<\/a>, Saksamaal<\/a>, Serbias<\/a>, Taanis ja Ungaris<\/a>.<\/p>\n Kuidas see lugu Sind end tundma pani?
