Xa Iinjongo Ezilungileyo Nokuba Yintoni Eyoyivula
Isizathu esivamekileyo sokusweleka kwesisu sihlobo esingaqhelekanga se- chromosome esibangela ukuba ukukhulelwa kungabi nako. Oku kuntshwenyeka, kodwa eqinisweni, kwiintlobo ezininzi ezibini eziye zagqithwa intlungu yokulahleka okunjalo iziphumo eziphezulu ziya kuvuka kwakhona kwaye ekugqibeleni zibe nomntwana onempilo. Ngenxa yoko, oogqirha abavumi ukucebisa uvavanyo lokulandela ukuzama ukufumana isisombululo sokuqala kwesisu, nangona abanye abazali abathembekileyo banokuziva ukuba ukuvavanywa kuya kubanceda bafumane ukuvalwa.
Ukuhlolwa kwe-Chromosome kuya kuba luncedo kakhulu emva kokulahleka kwamathambo amaninzi. Ukuze uyenze, isampuli yamathambo ukusuka ekuphumuleni komzimba kufuneka iqokelelwe kwaye ihlaziywe kwibhile. Umceli-mngeni, ngakumbi emva kokusweleka kwexesha elide, ngaba kunzima ukufumana isampuli esaneleyo ngaphandle kokuba ibhinqa liye lahlulwa kunye ne-curettage (i-D & C) -yinkqubo equka ukususa naziphi na izicubu ezingazange zidlule ngexesha lokukhulelwa kwesisu. Ukuba umfazi uqala ukuphuma ekhulelwe xa ekhulelwe kwaye uqinisekile ukuba unesisu, udokotela wakhe okanye umbelethisi angamxelela indlela yokugcina izicubu zihlaziywe.
Iphi i-Chromosome Testing Can reveal
Ngokusekelwe kwinani lama-chromosomes kunye nesakhiwo sabo, uvavanyo lwe-chromosome lunokuqinisekisa okanye ukulawula ukungaqhelekanga okubonakalayo njengobangela wokukhulelwa komzimba. Isizathu esivamekileyo se-chromosomal sokukhulelwa kwesisu si-trisomy. Ezinye ziquka i- triploidy , i-monosomy, i-tetraploidy, okanye i-malformations njenge- translocation- yonke into edlalwa yinto engafanelekanga kwindoda okanye iqanda, kunokuba izuzwe ngumzali.
Ngamanye amaxesha iziphumo ezibonisa i-chromosomes eziqhelekileyo kwintsana engenakukhulelwa ziza kuthathwa njengezigqibeleleyo kuphela ukuba umntwana usengumfana. Ngenxa yokuba ngaphezu kwesigamu seziphumo eziqhelekileyo ze-chromosom ephuma kwi-miscarriages ziba yinkwenkwekazi, abaphandi bakholelwa ukuba kuyinto evamile ukuba izicubu zikamama zingcolise iziphumo (nangona ubuchule banobuchule bunokunciphisa ubunzima bale nto ekhoyo).
Ngezizathu zeendleko kunye nezizathu zokunokwenzeka, akunakwenzeka ukugqiba ukuba ngaba iziphumo zokuvavanya zivela kumama okanye kwintsana kula maxesha.
Ukucwangciswa kwexesha elizayo lokukhulelwa
Kungakhathaliseki ukuba ziphi iziphumo, ukuba uvavanyo lwe-chromosome emva kokukhulelwa kwesisu ungaba nemibuzo malunga nendlela yokucwangcisa ukukhulelwa kwangaphambili. Ugqirha oxhasayo okanye umcebisi wezofuzo kufuneka akwazi ukuphendula imibuzo yakho. Kwaye ukuba iziphumo zakho zokuvavanya zibonakalise ukukhulelwa okuqhelekileyo okanye zingenakulinganiswa, kwaye uyaqhubeka ufumana ukulahleka kwezinto ezininzi, unokuba unqwenela ukubona ingcali onokukuvavanya ngenxa yezinye izizathu zokukhulelwa.
Ukuba iziphumo zakho zokuvavanya kwe-chromosome zityhila ukuba kukho ukungavumelekanga, iingxaki ziphezulu kunokuba yinkinga yexesha elilodwa. Akuthethi ukuba unomngcipheko okhulayo wokuba usana olunalo oluqhelekileyo kwikamva. Ininzi ye-chromosome engafanelekanga yiphumo lesiphene kwisahlulo seseli seberm okanye iqanda, kunye nexesha elininzi abayi kuphinda likhulelwe kwixesha elizayo. Ukwahlulelwa kulo mgaqo kukuba ukuba iziphumo zityhila ukuba umntwana usenokungenakulungelelaniswa, apho imeko oogqirha banokukucebisa wena kunye neqabane lakho ukuba uvavanywe kwimeko ebizwa ngokuthi i-translocation efanelekileyo.
Iibinibini ezifumana ukulahleka kwamathambo kunye nokuvavanya okuvakalayo kubonakalisa oku kwenzeka ngenxa yezinto ezingekho phantsi kwe-chromosome, kukho iindlela zokuzama ukukhulelwa kwexesha elipheleleyo kunye nosana oluphilileyo. Enye yale nkqubo yinkqubo eyaziwa njenge -diagnostic genetic diagnosis , kunye ne -vitro fertilization (IVF) . Kubiza kakhulu kwaye ngokuqhelekileyo kungagqitywa yi-inshurensi, kodwa ngokuqinisekileyo kuyayifaneleka kubini abatshatileyo abanomnqweno onzulu wokuba nabantwana bezinto eziphilayo.
