Trisomy 18

Munhu wese anoziva kuti hutano hwevanhu hunofanirwa zvikuru pamagadzirirwo e-chromosomes ari ari maviri muhutano hweDNA yevanhu. Asi kana pane zvakawanda zvezvo, somuenzaniso 3, zvino chiitiko ichi chinonzi "trisomy." Zvichienderana neizvipi kuwedzera kusati kwaitika kwakaitika, chirwere chacho chinonziwo. Kazhinji kacho dambudziko iri rinowanikwa mu13, 18 uye 21st pair.

Muchikamu chino, tichataura nezve trisomy 18, inonzi Edwards syndrome.

Nzira yekuona sei trisomy pa chromosome 18?

Kuti uone kuperevedza kwakadaro mukukudziridzwa kwemwana pamagenheji, sezvinonzi trisomy 18, zvinogona kuitwa chete nekucherechedza pa12-13 uye mavhiki gumi nematanhatu (funga kuti zuva racho rinotamirwa kuvhiki imwe). Inosanganisira biochemical blood test uye ultrasound.

Ngozi yemwana ane trisomy 18 mumwana kuti kuputsika kudarika kunowanikwa kwemahara hormone b-hCG isina kusununguka (chinonzi chorionic gonadotropin) yakatarwa. Kwevhiki imwe neimwe, chiratidzo chacho chakasiyana. Saka, kuti uwane mhinduro yakanyatsonaka, unoda kuziva nguva chaiyo yekubata kwako. Iwe unogona kutarisa pane zvinotevera:

Mumazuva mashomanana mushure mechiyero, iwe uchawana mugumisiro wauchazoonekwa, chii chiripo iwe unogona kuva ne trisomy 18 uye zvimwe zvisiri izvo mumucheche. Zvinogona kunge zvakaderera, zvisizvo kana zvakakwirira. Asi izvi hazvirevi kugadziriswa, sezvo nhamba dzinotaridzika dzinowanikwa.

Pangozi yakawanda, iwe unofanirwa kubvunza geneticist uyo achanyatsotsvaga tsvakurudzo yakawanda kuti aone kana iripo kana kuti haisi kukanganisa mune zvakagadzirwa nema chromosomes.

Zviratidzo zveTrisomy 18

Pamusana pekuti kuongorora kunokwereta-uye kunowanzopa chikonzero chisina kururama, kwete vose vakadzi vane pamuviri vanozviita. Zvadaro kuvapo kweEdwards syndrome mumwana kunogona kusarudzwa nezvimwe zviratidzo zvekunze:

1. Kuwedzerwa nguva yekuzvitakura (masvondo makumi mana), panguva iyo basa rekufukidzana kwe fetus uye polyhydramnios zvakaonekwa.
2. Paanenge aberekwa, mwana ane uremu hwemuviri (2-2.5 kg), unhu hwemukoko wakatarisa (dolichocephalic), chisingaoneki chiso chepamusoro (pasi pfupi, maziso mashoma uye muromo mutsva), uye zvibhakera zvakasungwa neminwe inoputika.
3. Kukanganiswa kwemakumbo uye kusakanganiswa kwemukati maviri (kunyanya mwoyo) kunoonekwa.
4. Sezvo vana vane trisomy 18 vane kukura kwakanyanya mumuviri kusakanganisika, vanorarama kwechinguva chiduku (mushure memakore 10 chete 10% yavo inoramba iri).
