The chidzoke upenyu hutsva, kana genetics chinodiwa panguva pamuviri

Munguva dzazvino vabereki kana kuronga pamuviri, kazhinji vanonyatsoteerera, pasi chiratidzo chii nyeredzi iri remangwana mwana wavo, kana chii uriri, anoziva chose kuti chokwadi kuti unofanira kutanga kupfuura zvinodiwa nemiedzo uye kuwana mazano kubva genetics.

Dzinza rako - sayenzi yedzinza, iyo vanachiremba specialized nemagene miedzo zvainanga kuziva majini dzakasikwa, izvo zvinogona kukonzera vachiberekwa zvirwere, enhaka. Nokudaro, genetics pamuviri, zvinoita kutsvakurudza zvirwere zvakasiyana-siyana Kutamiswa nhaka sepakutanga pamuviri uye panguva yepamuviri.

Pari, vakawanda vemhuri kutsvaka mazano kubva vanachiremba pamusoro genetics zvirwere zvakasiyana-siyana. Chokwadi, genetics kubvunza panguva pamuviri zvakakodzera, kutanga, kusarudza munhu zvichibvira ngozi kuvapo kwezvirwere zvinogona nhaka. Physician-geneticist mufambiro kuferefeta zvose zvakakodzera kuti tizive pamberi mwana asati aberekwa kuti magene pathologies.

Saka, kana vachironga pamuviri, uyewo kuvapo pamuviri, kuti gayinakorojisiti zano narwo zvokurapa uye pamuviri magene tsvakurudzo. Kudzidza uku conventionally rakakamurwa mapoka makuru matatu:

- invasive muedzo kuvhiyiwa, nokuda iyo Mucheka uye masero fetus;

- dzisiri invasive tsvakurudzo, kureva tsvakurudzo pasina kuvhiya kupindira, izvo zvinosanganisira Ultrasound uye Doppler vascular ropa uye placenta.

- mumwe achivhara nzira chirwere rinoumbwa kuona ropa zvinhu mai, uyo anogona kutaura vachiberekwa malformations ari mudumbu.

Tinogona kutaura kuti genetics panguva pamuviri kunosanganisirawo kusarudza nemagene mapoka ngozi, zvinosanganisira vanhu vane refu mukana ane nokuberekwa nevana enhaka zvirwere. Mapoka njodzi idzi dzinosanganisira:

- Vakadzi vane idzokororo kupfupfudzika kana kurashikirwa pamuviri;

- vakadzi akanwa panguva pamuviri kugadzirira kuva chikamu teratogenicity;

- Vakadzi pamusoro-matatu nemashanu, uye varume vane zera kupfuura makumi mana makore;

- vabereki vane zvirwere zvakasiyana, zvishuvo nhaka;

- Vabereki vari consanguineous muchato;

- vabereki vakaona migumisiro nemwaranzi kana makemikari.

Kana pamuviri kunoitika gayinakorojisiti anotumira mukadzi ari chikamu Ultrasound. Wokutanga Ultrasound kupfuure gestation mavhiki mashanu, asi wechipiri unofanira kuenda hapana paya pane gumi vhiki pamuviri. Izvi imhaka yokuti munhu geneticist panguva nhumbu mukadzi ane mukana uyu izwi kuti chirwere fetus malformations uye kudoma vamwe kuchinja ayo, izvo zvingava zvokurwara okutodza. Muchiitiko chino, nyanzvi richashandiswa chirwere nzira iri amniocentesis uye biopsies. Zvinonzi Dzakamukurudzirawo zvakaitika nezuva retatu Ultrasound nguva twenty- vhiki mbiri pamuviri kuziva abnormalities mu chiso kukura, maoko nemakumbo uye nhengo dzomukati kwemwana. Muchiitiko chino, genetics, pamuviri kubvumira pakurapa mwana achiri mudumbu, kana mazano kwokurapa pashure pokuberekwa kusvikira apora.

Zvinofanira kurangarirwa kuti chete misoro kudzidza Pedigree geneticist, nhoroondo zvokurapa uye utano hune vakadzi vabereki vose zvinoita kushandisa zvakakodzera nzira kuongororwa pamuviri uye kusarudza nzira yakakodzera kana vachimuka kudiwa. Saka, genetics panguva yepamuviri kudzivirira kuberekwa vana vakaremara siyana.
