I-Down Syndrome Facts

Mayelana ne-Commonly Genetic Disorder

I-Down syndrome yisifo esiwumzimba esibangelwa ukukhubazeka kwe-chromosome 21 eyenzeka ngenxa yokuhlukaniswa kwe-cell engavamile. Isiyaluyalu senza izinkinga zengqondo nezentuthuko ezihluka ngobunzima. Kungabangela nezinkinga ezinkulu zempilo ezinjengokukhubazeka kwenhliziyo.

Kukhona abangaba ngu-400,000 baseMelika abane-Down syndrome. Ngokusho kweNational Down Syndrome Society, 1 kuzo zonke izingane ezingu-691 e-United States zizalwa nge-Down syndrome.

Laba bantwana abangaba ngu-6 000 abazalwa nge-Down syndrome unyaka ngamunye. La maqiniso asheshayo azokunika ukuqonda okungcono kwe-Down syndrome, isifo se-chromosomal esivamile kakhulu.

Izimbangela

Amaseli omuntu ngokuvamile aqukethe ama-chromosomes angu-23. I-Down syndrome imiphumela uma i-chromosome 21 ikhiqiza izinto ezengeziwe zofuzo. Kunezinhlobo ezintathu ezahlukene zohlobo lwe-Down syndrome:

• I-Trisomy 21 . Lokhu kungavamile okwenzeka kakhulu kwe-chromosomal kubantwana. Kuyenzeka uma ingane inamakhophi amathathu e-chromosome 21 kumaseli akhe kunokuba amabili. Ilandisa amaphesenti angama-95 ama-Down syndrome amacala. I-chromosome eyengeziwe ivela kumama ngamaphesenti angu-88 esikhathi futhi kusukela kubababa abangu-12 yesikhathi.
• I-Mosaic Down syndrome . Leli fomu elingavamile le-Down syndrome libala amacala angu-2 kuya kwangu-3 wamacala. Ezinye, hhayi zonke, amaseli anakho ikhophi eyengeziwe ye-chromosome 21.
• I-Translocation Down syndrome . I-Chromosome 21 ifinyelela kwenye i-chromosome, ngaphambili noma ekukhulelweni. Cishe amaphesenti angama-75 alezi zinguquko ezingalinganiselwe ziyi- novo , okusho ukuthi zenzeka ngengozi. Amaphesenti angu-25 okudluliselwa kwezimali empeleni azuzwe njengefa lomzali. Umzali waziwa ngokuthi "othintekayo ophethe kahle," okusho ukuthi abuye ahlele kabusha izinto eziphathelene nezofuzo, hhayi izinto ezengeziwe zofuzo. Umphathiswa olinganiselayo akabonisi izimpawu ze-Down syndrome, kodwa akwazi ukudlulisela ezinganeni.

Zonke izinhlobo ezintathu ze-Down syndrome ziyizimo zofuzo, kodwa kuphela amaphesenti angu-1 e-Down syndrome amacala adluliselwa kusuka kumzali kuya kwengane ngokusebenzisa izakhi zofuzo.

Izingozi Zezingozi

Abanye abazali bafaka ingozi yokukhulelwa ingane ene-Down syndrome. Ubudala buyinto eyodwa. Amathuba okuba nengane nge-Down syndrome yanda njengoba owesifazane edala.

Owesifazane oneminyaka engu-35 ubudala, ingozi ingu-1 ngo-385. Uma uneminyaka engama-40, ingozi ingu-1 kwangu-106. Ngama-45, ubungozi ku-1 kwangu-30. Amaphesenti angu-80 kuya kwangu-85 wezingane ezine-Down syndrome azelwe abesifazane ngaphansi kuka-35.

Ukwengeza, owesifazane onomntwana oyedwa nge-Down syndrome cishe unomunye ingane ene-Down syndrome. Abesilisa nabesifazane nabo bayakwazi ukudlulisela lesi sifo ezinganeni ngokudluliselwa kwemikhakha uma bephethe abathwali abathintekayo.

Ukulindela Ukuphila

Eminyakeni yamuva ukulinda komuntu kubantu abane-Down syndrome kuye kwashintsha kakhulu. Ngo-1983 isikhathi sokuphila saba ngu-25; namuhla kunama-60. Cishe amaphesenti angu-25 emikhono nge-trisomy 21 ekupheleni kokukhulelwa noma ukuzalwa komzimba. Amaphesenti angu-85 ezinsana ezine-Down syndrome zisinda eneminyaka engu-1 ubudala.
